Thanks for the report. This is also [perl #133295]. Apparently
gdbm has fixed the crash that this test checks for, but doesn't
report errors properly either.

The issue seems somewhat tricky with improvements suggested on
both the gdbm and perl side.

I guess that last gdbm fix can't be easily cherry-picked as it changes
the interface?

Might be worth checking what Petr Pisar ended up doing for Fedora.
