I can still reproduce the crash in an SMP amd64 xen domain with
the first test script (the one by Jamil Djadala) in the report and
vm.overcommit_memory=2 on current sid: perl 5.10.0-10, glibc 2.7-11. The
kernel is from Etch, though, which actually might matter. Reopening
anyway.
The bug doesn't usually show up on the first try; see below. It looks
like the system runs out of memory doing the perl_clone(), and something
can't quite cope. The resulting core file is obscenely big. The number
of Perl_*_dup calls and the final crashing place in the stack trace varies.
Roberto, do you know something more about this, or what was it that
prompted you to close the bug?
