Bug#1058703: getsockopt test failures in JRuby on aarch64

[Jérôme Charaoui]

Package: libjffi-jni
Version: 1.3.12+ds-1
Severity: normal

Hello,

I'm encountering unexpected failures when running the JRuby testsuite on 
aarch64 with libjffi-jni_1.3.12+ds-1:

These failures are *not* present when running the testsuite with 
libjffi-jni_1.3.9+ds-6 shipped in bookworm, nor with the upstream-built 
1.3.12 binary version of this library.

I'm not sure but I suspect maybe some element deeper in the build chain 
changed between bookworm and sid, causing these new issues.

These tests pass fine on amd64.

Thanks,
