Segmentation fault during `make check'
Hi all, I encountered a segmentation fault that happens sporadically during a 'make check' run. See https://gitlab.com/lilypond/lilypond/-/merge_requests/683 for some context. It is not reproducable with a specific snippet, but I could reproduce it on top of a failed 'make check' run by running the 'lilypond' command that failed. Unfortunately, it seems somehow related to optimization, because the identical setup with an unoptimized lilypond binary (compiled in a different tree from same 'master') does not fail. Pretty hard to track it down... I do not know if the stack trace of the optimized binary is useful, but: #0 0x7780aa1c in scm_dapply (proc=0x404, arg1=, args=0x7fffec751010) at eval.c:4989 #1 0x55669b84 in Engraver::internal_make_grob(scm_unused_struct*, scm_unused_struct*, char const*, int, char const*) (this=, symbol=0x72fc4920, cause=cause@entry=0x404, file=0x558d2848 "/home/michael/lilypond/lily/paper-column-engraver.cc", line=73, fun=0x558d2f28 "make_columns") at /home/michael/lilypond/lily/engraver.cc:146 #2 0x55669ea7 in Engraver::internal_make_column(scm_unused_struct*, char const*, int, char const*) (this=, x=, file=, line=, fun=) at /home/michael/lilypond/lily/engraver.cc:166 #3 0x55758b9e in Paper_column_engraver::make_columns() (this=this@entry=0x561a59b0) at /home/michael/lilypond/lily/paper-column-engraver.cc:73 #4 0x55758e3d in Paper_column_engraver::initialize() (this=0x561a59b0) at /home/michael/lilypond/lily/paper-column-engraver.cc:82 #5 0x5584c317 in Callbacks::trampoline(scm_unused_struct*) (target=) at /home/michael/lilypond/lily/include/callback.hh:114 #6 0x7780ad86 in scm_dapply (proc=0x70f7a220, arg1=0x7fffec7ad290, args=0x404) at eval.c:5019 #7 0x5584b5b1 in translator_each(scm_unused_struct*, scm_unused_struct*) (method=, list=) at /home/michael/lilypond/lily/translator-group.cc:45 #8 0x5584b5b1 in recurse_over_translators(Context*, scm_unused_struct*, scm_unused_struct*, Direction) (c=c@entry=0x56573340, ptr=0x70f7a220, tg_ptr=tg_ptr@entry=0x70f7a240, dir=dir@entry=DOWN) at /home/michael/lilypond/lily/translator-group.cc:211 #9 0x5584b9d2 in Translator_group::create_child_translator(scm_unused_struct*) (this=, sev=) at /home/michael/lilypond/lily/translator-group.cc:169 #10 0x5584c3b5 in Callbacks::trampoline(scm_unused_struct*, scm_unused_struct*) (target=, ev=) at /home/michael/lilypond/lily/include/callback.hh:124 #11 0x7780afaf in scm_dapply (proc=0x70f804a0, arg1=0x7fffece1cfc0, args=0x7fffec7adbf0) at eval.c:5021 #12 0x55652627 in Listener::listen(scm_unused_struct*) (ev=, this=) at /home/michael/lilypond/lily/include/listener.hh:108 #13 0x55652627 in Smob_base::smob_trampoline<&Listener::listen>(scm_unused_struct*, scm_unused_struct*) (self=, arg1=) Maybe related to garbage collection?

Pretty hard to track it down... Ouch, I cannot reproduce it even with a freshly compiled lilypond from same master, with same 'configure' settings. (--enable-checking) The binarys, however, are not byte-identical. I though we managed some time ago to have completely reproducable builds? Luckily I still have the failing binary here... Michael

Greetings, My name is Al. I am a retied design engineer. 15 years embedded in assembly followed by 20 in the Windows environment programming C and its derivatives. Since retiring I moved all my development machines to linux and started looking at opensource projects to keep my hand in. I am also an aspiring musician and have used Finale, MuseScore and lilypond with Frescobaldi to a great extent. I am attempting to compile lilypond 2.22 on xubuntu 20.04 using "make all". I get the error: /usr/bin/ld: cannot find -lguile Should be a simple thing to set a path to the guile 1.8 libraries - but I cannot find them, either. Would someone be so kind as to offer some advice on compiling lilypond? Thanks, Al
Re: guile libraries
There's a quick path for an underperforming lilypond: sudo apt install guile-2.2-dev. The slow path for good performance is installing guile-1.8 from its git repository, which I never did.

Pretty hard to track it down... I'm confused here: Was the initial segmentation fault also on master or with MR !683 applied? > I do not know if the stack trace of the optimized binary is useful, but: > > #0 0x7780aa1c in scm_dapply (proc=0x404, arg1=, > args=0x7fffec751010) > at eval.c:4989 > #1 0x55669b84 in > Engraver::internal_make_grob(scm_unused_struct*, scm_unused_struct*, > char const*, int, char const*) (this=, > symbol=0x72fc4920, cause=cause@entry=0x404, file=0x558d2848 > "/home/michael/lilypond/lily/paper-column-engraver.cc", line=73, > fun=0x558d2f28 > "make_columns") at /home/michael/lilypond/lily/engraver.cc:146 This is in the branch of "if (ly_is_procedure (creation_callback))", which probably means two things: 1. It might be related to the changes in MR !683 because my understanding is that Graphiz is the only user of ly:set-grob-creation- callback. 2. Depending on whether you hit the fault when processing input/regression/graphviz.ly (my understanding is you don't?), the creation callback is not reset after a session (= an input file) ends.

-lguile -- cannot be found [SOLVED]
OK, it looks as though hijacked a previous thread. Sorry about that. Although I did install the guile-2.2-dev I still get the same error: /usr/bin/ld: cannot find -lguile In config.make is the following line: CONFIG_LIBS = -lglib-2.0 -L/usr/local/lib -lguile I solved my problem by running "locate libguile" and ended up pointing that offending line to "/usr/local/include" instead of "/usr/local.lib". thanks, Al There's a quick path for an underperforming lilypond: sudo apt install guile-2.2-dev.

Most likely you have to compile guile 1.8 by yourself since it is no longer available universally as a distribution package. Starting with guile's git repository as a source is probably best: https://git.savannah.gnu.org/cgit/guile.git/log/?h=branch_release-1-8 * Clone this repository and check out the `branch_release-1-8` branch. * Run the `./autogen.sh` script. * Run ./configure --prefix=/usr/local/opt --disable-error-on-warning make make install (adjusting `--prefix` to your taste). * Call LilyPond's `configure` script like the following. PKG_CONFIG_PATH=/usr/local/opt/lib64/pkgconfig \ ./configure ... Werner
Re: Segmentation fault during `make check'
Hi Jonas, I do not know if the stack trace of the optimized binary is useful, but: #0 0x7780aa1c in scm_dapply (proc=0x404, arg1=, args=0x7fffec751010) at eval.c:4989 #1 0x55669b84 in Engraver::internal_make_grob(scm_unused_struct*, scm_unused_struct*, char const*, int, char const*) (this=, symbol=0x72fc4920, cause=cause@entry=0x404, file=0x558d2848 "/home/michael/lilypond/lily/paper-column-engraver.cc", line=73, fun=0x558d2f28 "make_columns") at /home/michael/lilypond/lily/engraver.cc:146 This is in the branch of "if (ly_is_procedure (creation_callback))", which probably means two things: thanks for spotting this. 'creation_callback' is currently not protected against garbage collection, unlike the other debugging callbacks. I will prepare a separate MR to fix this. Michael
Re: guile libraries
Hello Al, The problem is that guile-1.8 is not supported by modern distros anymore. I’m not sure if Ubuntu handles this well, but under Debian you can fetch the source code with apt-get source lilypond. (Ubuntu just uses the version maintained by Debian, so I think this should work out.) This will download the source code as used by Debian, which means that it will come bundled with it’s own guile1.8 version. It also gives you the Makefile debian/rules for building and packaging. So you can just do apt-get build-dep lilypond To install the dependencies needed for building, and apt-get source lilypond to fetch the source code. Of course you can also try to install guile-1.8-dev from Jessie/Xenial. Cheers, Valentin Am Montag, 15. März 2021, 17:54:16 CET schrieb Al Rice: > Greetings, > > My name is Al.

Re: guile libraries
Thanks. I have actually managed to build the necessary 1.8 libraries and am now able to compile without error.
