Source: gcc-9
Version: 9.1.0-8
Severity: important
Control: affects -1 gcc libglib2.0-0
Hiya,
I saw this on Ubuntu (9.1.0-8ubuntu1) but I've also reproduced this with
9.1.0-8 on sid (w/gcc-defaults from experimental to use gcc-9 by
default).
clutter's tests hang like this:
0x00007ffff7b316f4 in __GI___poll (fds=0x5555558d0420, nfds=2, timeout=-1) at
../sysdeps/unix/sysv/linux/poll.c:29

at actor-offscreen-redirect.c:172
Here's the bit of code.
https://sources.debian.org/src/clutter-1.0/1.26.2+dfsg-10/tests/conform/actor-offscreen-redirect.c/#L172
It's adding some stuff to a main loop and expecting it to finish when a
particular signal handler is called.
There's obviously a lot of code going on here (this isn't anything like
a minimal testcase, and glib2.0's own testsuite & autopkgtests pass so
it's not like GMainLoop is completely broken).
I found an upstream report which I suspect is the same thing:
https://gitlab.gnome.org/GNOME/clutter/issues/6
Things which make it work again
- Building glib2.0 w/gcc-9 -O1 (and -O0)
- Building w/gcc-8 (obviously)
Happy to help try to narrow this down to the optimisation that's
breaking glib and/or the code in glib that's breaking the optimisation.
Maybe in person at Debconf. For now I'm going to upload a glib2.0 that
builds with gcc-8 explicitly.
Cheers,

Closes: 931921
Changes:
clutter-1.0 (1.26.2+dfsg-11) unstable; urgency=medium
.
* Team upload
* d/p/clutter-tests-conform-Fix-actor-offscreen-redirect.patch:
Apply patch from mutter's fork of clutter to fix a faulty test.
This recently regressed when changes to gcc optimizations resulted
in GLib code leaving different uninitialized stack contents, causing
the test to be attempted (and hang), instead of never actually being
attempted (as it did previously). (Closes: #931921)
* d/tests/installed-tests: Use AUTOPKGTEST_TMP instead of
deprecated ADTTMP
* d/tests/build: Add a superficial build test to verify that
libclutter-1.0-dev works.
This does not exercise static compilation because not all dependencies
are available as static libraries.
* Set Rules-Requires-Root to no
* Don't run dbus-run-session and xvfb if we are going to skip build-time
tests due to nocheck
* Make libclutter-1.0-dev Multi-Arch: same.
This is not yet directly useful, because some dependencies are not.
* Make the documentation Multi-Arch: foreign
* Standards-Version: 4.4.0 (no changes required)
* Use debhelper-compat 12
- Move installed-tests to default libexecdir, /usr/libexec
* d/p/clutter-tests-conform-Fix-actor-offscreen-redirect.patch,
d/p/gdk-Ensure-surface-buffer-scale-is-set.patch:
Mark patches as applied upstream
