Hi all,

I am stuck in the following segfault problem for several days now and quite desperate...
Since some point (don't know if due to a CPAN upgrade or any other change to my Ubuntu 9.10), my Perl program keeps crashing with a core dump.

Trying to update some CPAN modules, a test script of Devel::Declare also caused a segfault: t/method-installer-runtime.t at this lines:
...
method foo {
    $_[0]->method
}
...

With gdb, I tracked down the problem to Sub::Name: 

Core was generated by `/usr/bin/perl t/method-installer-runtime.t'.
Program terminated with signal 11, Segmentation fault.
#0  0x0057a561 in XS_Sub__Name_subname () from /usr/lib/perl5/auto/Sub
+/Name/Name.so

Doing some research, in the Perl porters mailing list I found that Sub::Name is "known problematic"...
Besides that, there are two open bugs including patches for Sub::Name, but they are not about segmentation faults. In reply to one patch Sergey Aleynikov says: "this seems to solve problem with local()ized subref assigments to globs". Might that be relevant for me?

My Perl (compiled from Debian source) version is: 

This is perl 5, version 12, subversion 0 (v5.12.0) built for i486-linu
+x-gnu-thread-multi-64int-ld
(with 27 registered patches, see perl -V for more detail)

Does anybody have some hints for me where the problem lies?
