The --gc-sections linker option triggers a bug in the gold linker[1] which results in a bogus .eh_frame section making debugging harder: gdb backtraces stop at a library built by systemd and libunwind simply segfaults.
Workaround by that bug by removing the option. The additional disk space saved by this option is marginal anyway (less than 1%). To illustrate this, see this `du -ks` on the installed files: 83548 without-gc-sections/install 25796 without-gc-sections/install-strip 83432 with-gc-sections/install 25752 with-gc-sections/install-strip [1]: https://sourceware.org/bugzilla/show_bug.cgi?id=17639 https://bugs.freedesktop.org/show_bug.cgi?id=86666 --- configure.ac | 1 - 1 file changed, 1 deletion(-) diff --git a/configure.ac b/configure.ac index bd3cc0e..8d926be 100644 --- a/configure.ac +++ b/configure.ac @@ -219,7 +219,6 @@ AC_SUBST([OUR_CPPFLAGS], "$with_cppflags $sanitizer_cppflags") CC_CHECK_FLAGS_APPEND([with_ldflags], [LDFLAGS], [\ -Wl,--as-needed \ -Wl,--no-undefined \ - -Wl,--gc-sections \ -Wl,-z,relro \ -Wl,-z,now \ -pie \ -- 1.9.1 _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
