Source: gtk4
Version: 4.10.3+ds-1
Severity: important
Tags: upstream ftbfs
Justification: fails to build from source
X-Debbugs-Cc: debian-ri...@lists.debian.org
Dear maintainer,
As part of the riscv64 bootstrap, I have been trying to build and import
gtk4 (involves building it with a mix of the official archive and the
old debian-ports archive). Unfortunately it fails to build from source
with a failure in the testsuite:
| 262/722 gtk:gtk / templates
ERROR 8.58s killed by signal 5 SIGTRAP
This only happens for the wayland tests, not for the x11 ones. Here is
the corresponding test details and my attempt at using gdb:

The segmentation fault appears because "surface.display" is
0xcfcfcfcfcfcfcfcf, which sounds like some memory poisoning.
I believed that the problem is fully reproducible (running the
individual test like above definitely is), but I start to have some
doubts. It appears that the issue was already present in the latest
builds on the debian-ports archive:
https://buildd.debian.org/status/fetch.php?pkg=gtk4&arch=riscv64&ver=4.10.3%2Bds-1&stamp=1683828518&raw=0
https://buildd.debian.org/status/fetch.php?pkg=gtk4&arch=riscv64&ver=4.10.4%2Bds-1&stamp=1686004425&raw=0
https://buildd.debian.org/status/fetch.php?pkg=gtk4&arch=riscv64&ver=4.10.4%2Bds-2&stamp=1689784927&raw=0
I have also noticed that the issue also appeared on some architectures,
maybe with less probability:
https://buildd.debian.org/status/fetch.php?pkg=gtk4&arch=armel&ver=4.10.3%2Bds-1&stamp=1683820072&raw=0
https://buildd.debian.org/status/fetch.php?pkg=gtk4&arch=mips64el&ver=4.10.5%2Bds-3&stamp=1691410067&raw=0
https://buildd.debian.org/status/fetch.php?pkg=gtk4&arch=mipsel&ver=4.10.5%2Bds-3&stamp=1691412439&raw=0
I have used lower version for which the issue appeared, but if it is
more or less random, it could be something even older, or a bug
somewhere else in the stack.
Any ideas about the issue or how to debug it is welcome.
Regards
Aurelien
