Package: libunwind8
Version: 1.7.2-1
Severity: serious
Justification: results in FTBFS in unrelated packages
X-Debbugs-Cc: debian-...@lists.debian.org
User: debian-...@lists.debian.org
Usertags: armhf
The test suite for the libportal package, like many packages that use
GUI libraries, is run under Xvfb:
xvfb-run -a -s "-noreset" dh_auto_test -- $(options)
In a recent upload this failed on armhf, and only armhf: the actual
tests appear to have all succeeded, but then xvfb-run exited with status
1 anyway. I am able to reproduce this on the armhf porterbox amdahl.
A simplified reproducer is:
xvfb-run -e /dev/stderr -a -s "-noreset" true
which should exit 0, or
Xvfb :42 -noreset -nolisten tcp
which should start and wait until terminated (assuming the socket for :42
is available).
Running `gdb --args Xvfb :42 -noreset -nolisten tcp` produces this
backtrace inside libunwind:

This appears to be a regression between trixie (where xvfb-run and Xvfb
work as I had expected) and sid (where Xvfb crashes).
For whatever reason, if I run xvfb-run with arguments that include
`-s "-screen 0 1280x1024x24 -noreset"` instead of just `-s "-noreset"`,
Xvfb doesn't crash.
The system information below is from an armhf chroot on amdahl where I
could reproduce this.
