Source: libadwaita-1
Version: 1.6~beta-1
Severity: serious

libadwaita-1 since 1.6~beta-1 failed to build from source on the i386 buildd,
with a test failure that does not seem to occur on any other architecture:

I've retried the build to see whether this is reproducible, but a
segfault in a similar place was seen multiple times for 1.6~beta-1,
so it probably is.
