Test `09arrays.t` segfaults

Hello, with 3.18.0, I get following

[   44s] Test Summary Report

That is namely on aarch64, but I have seen it on x86_64 as well:
https://build.opensuse.org/package/live_build_log/devel:languages:perl/perl-DBD-Pg/openSUSE_Tumbleweed/x86_64

Not sure when and why it segfaults. Is that known?

What version of gcc are you using, @pgajdos ?

Also, what is your PostgreSQL version?

[pgajdos]

gcc14 and postgresql17. You can see that among other build info environment in the log I have referenced.

I swear I looked and could not find the gcc version anywhere in the log output!

I suspect this might be an issue with PostgreSQL 17.x. Can you do a test build with PostgreSQL 16.x?

I suppose it could be specific to some Perl version, too...

Similar error (although all tests actually pass) here on OpenBSD.amd64 with PostgreSQL 17.5 on Perl 5.41.13 and compiled with Clang 16.0.6:

https://matrix.perl-magpie.org/results/5a6ba0ea-3bef-11f0-b8bf-d95464aa5f27

Included in its test output is this message:
