Window + fork + Math::Pari = pain

bsb has asked for the wisdom of the Perl Monks concerning the following question:

Hello,

I've reported a bug in RT with Crypt::Random but since perl is aborting, maybe I should report it somewhere else. RT#25309

What do you think?

update: Math::Pari seems to be the problem:

perl -MMath::Pari -e "fork"

`fork` doesn't really have anything to do with it. It's about threading. Keep in mind that `fork` creates a new thread in Windows, not a new process. The problem can be triggered more directly using: `perl -MMath::Pari -Mthreads -e "threads->create(sub{})->join();"` [download] It appears that Math::Pari is not thread-safe.	[reply] [d/l] [select]

I'm using the Math::Pari ppm but it's build process seems to only use the unix source PariBuild.pm `sub download_pari { my ($srcfile, $force) = (shift, shift); my $host = 'megrez.math.u-bordeaux.fr'; my $dir = '/pub/pari/unix/'; my($ftp, $ua, $base_url); ...` [download] There is a windows build at ftp://megrez.math.u-bordeaux.fr/pub/pari/windows/ which may avoid the problem although I haven't yet tried to use it. Thanks for your reply	[reply] [d/l]

If the module isn't thread safe, a special windows build wouldn't avoid the problem.	[reply]

That also segfaults in linux.	[reply]
