I was never able to find a solution, so if any one can look and give any
suggestion, I will appreciate

I just rebuilt the old 1.37 and it is reporting the same errors,
while in 2020 it was passing all the tests
so it seems something else is playing a role here
very puzzling
Hi Marco,
I noticed that the build is generating libtool wrapper sources, executables,
and shell scripts under .../build/tests/.libs/ for the test programs, so if
that also happens with 1.37, that raises my suspicions that what is failing
is something to do with those wrappers and Cygwin libtool mods.
Another possibility is that the failures are caused by a Cygwin bug
introduced since 2020. There have been several bugs in Cygwin 3.5.3 that
have been fixed. Since 3.5.4 hasn't been released yet, you could try the
latest test release of 3.6, which has all the bug fixes.
FWIW, I tried running t-lock.exe under strace and saw "SetThreadName:
SetThreadDescription() failed", followed quickly by a SIGSEGV. That again
suggests a possible Cygwin bug.
Thanks Ken,
Great suggestion - also did strace on t-printf from 1.50 tests/.libs with
src/.libs in the path to pick up test dll and got a loop due to a SEGV on
0000000500000000 - makes interesting reading, but does not mean much to me -
terminated it eventually.
Attached log has been reduced by ~156MB and 2.5MLOC and lightly sanitized.
However, I see no changes since to SetThread related stuff since misc_funcs.cc
in 2022.
There may be some issues with Windows error or exception handling, so I will
retry under cygwin... 3.6.0-115...
No changes after upgrading all cygwin... packages to test 3.6.0-139... including
also taking the precaution of running:
$ env -i PATH=build/src/.libs:/usr/bin:/bin:/sbin:/usr/sbin strace ./t-printf
...
$ head /proc/version
CYGWIN_NT-10.0-19045 version 3.6.0-0.139.g7e3c833592b2.x86_64
(runneradmin@fv-az534-931) (gcc version 11.4.0 (GCC) ) 2024-06-16 15:01 UTC
So perhaps the SetThreadDescription stuff needs another look?
Anyone familiar with that?
I cut down various parts of the program, and finally narrowed it down to gpgrt
allocation or cygwin allocation corrupting the stack so return fails.
See attached gdb log.
