I can't reproduce this failure. Could you provide a backtrace, preferably with debugging symbols, for the segfault, please? You might find the Devel::bt module from CPAN useful in doing so.

Indeed, not reproducable under perlbrew's perl

Reproducable under vendor perl:

Note, that when I reported the bug, 10.04 was supported distribution, now it's unsupported (end of life).
however I think Ubuntu Server 10.04 is still supported (but I did not test on it)
