Well, when I build the same tarball on Cygwin 2.9.0 64-bit, I get
much better results (10 failures, not 43 failures).
Hi Bruno,
Please note that latest bison built and passed all checks on latest
Cygwin 32.
The issue is only with Cygwin 64.
I consistently reproduced the SEGV @ 0x0000000100000000 with trashed
stack, in a gdb script.
I reproduced the same results in both environments with bison 3.8/3.8.1
and gcc 10.2.0/11.2.0, to eliminate other possible concerns, over a few
days, before asking for help on bug-bison!
How did you build that package?
I built using latest Cygwin 3.2.0 with gcc 10.2.0 and ~150 Cygwin
...-devel packages available, using cygport --debug for logging, but
otherwise default package build with autoreconf, configure, make, check,
same as Cygwin 32 bison.
I am currently rebuilding using just straight
$ configure --disable-silent-rules && make && make check
into a parallel dummy-build dir (with logs), to hopefully get more
diagnostically useful check logs.
I will also redo cygport with --disable-silent-rules after those builds
and checks complete (in a few hours).
