I observe a random crash at the end of t/04idents.t:

$ while perl -Ilib t/04idents.t; do :; done

Segmentation fault (core dumped)

On my x86_64 virtual machine it takes no longer than 50 iterations to get the segfault:

I have installed:

perl-libs-5.40.1-515.fc42.x86_64
perl-DBD-SQLite-1.76-2.fc42.x86_64

It could be a bug in sqlite or perl-DBD-SQLite.
