Subject:

packaged script crashes when creating a new thread

Hi, I'm trying to package a multithreaded script with pp, and the executable crashes with "munmap_chunk(): invalid pointer" and a backtrace (see attached full output) when calling threads->create(). The script works fine when not packaged. This error can be triggered with a simple one-liner like this: pp -e 'use threads; threads->create(sub {})->join()' I'm using PAR 0.977 and PAR::Packer 0.977 with perl 5.8.8 i486-linux-thread-multi. Regards, Michal

I've experienced similar trouble with threads and pp. I'm sorry, I have not solution. This is just a heads-up that it's a known bug and you're not ignored. (Not entirely anyway :) Cheers, Steffen

This should be fixed by PAR::Packer 0.979 which is on its way to CPAN.
