Assuming hppa is 32-bit, that's an array of ((size_t) -1) 4-byte elements,
so probably some uninitialized or incorrect number is being used as an
array length.

A backtrace from this crash (it's a SIGTRAP, so it should leave a core
dump) will probably narrow down where to look.

This test succeeds on 32-bit release architectures like i386 and armhf,
so there must be some hppa-specific reason why it's trying to use a
nonsense array length. Is there something unusual about hppa memory layout
or alignment or anything like that?

In the buildd log at
https://buildd.debian.org/status/fetch.php?pkg=glib2.0&arch=hppa&ver=2.74.0-1&stamp=1663637461&raw=0
it doesn't seem to have DEB_BUILD_OPTIONS=nocheck, but also doesn't seem
to be running tests at all? Has some toolchain package been modified to
make it skip tests on this architecture, or something like that?

In a previous buildd build
https://buildd.debian.org/status/fetch.php?pkg=glib2.0&arch=hppa&ver=2.74.0-1&stamp=1663629476&raw=0
the test failed in the same way you reported.
