Bug#1087564: pcre2: FTBFS on 32-bit: test failures, memory allocations smaller than expected
Source: pcre2
Version: 10.44-2
Severity: serious
Tags: ftbfs
Justification: fails to build from source (but built successfully in the past)

shows lots of test failures that look like this:

> Memory allocation - code portion : 17
armel has a different failure mode (some of the tests crash) which I have
reported as a separate bug - that's out of scope here. All of the other
32-bit architectures (i386, hppa, powerpc, x32) show symptoms similar to
armhf, which makes me think this is a general 32-bit problem rather than
being architecture-specific (and armel would probably have the same issue
if its tests hadn't crashed first).
Is this perhaps just an overly-strict test that is making assumptions
about the size of data structures on 64-bit architectures, which aren't
going to be true on 32-bit because pointers and 'long' are smaller there?
10.44-1 in experimental previously failed with similar symptoms.
