| Subject: | Perl 5.10/x86-64 crash with POE::Component::Schedule |
Here is attached a script that uses both POE::Devel::Top and
POE::Component::Schedule.
The script makes Perl crash (segmentation fault) at the end of the first
display of the P::D::T report.
When the POE::Devel::Top->spawn call is disabled in the script, Perl
does not crash.
POE 1.289
POE::API::Peek 2.15
POE::Devel::Top 0.01
POE::Component::Schedule 0.95
This is Perl 5.10.0 for x86_64-linux-gnu-thread-multi running on Ubuntu
9.10.
