Since 5.16.0, perl segfaults when using glob in multi-threaded environment.
This has been reported to upstream as
<https://rt.perl.org:443/rt3/Ticket/Display.html?id=117823>;. Tests case:
use warnings;
use strict;
use threads;
use threads::shared;
my $nthread = 20;
sub work {
foreach (1..10000) {
my @files = <*.supp>;
}
}
my @threads;
foreach my $i (1..$nthread) {
push @threads, threads->create(\&work);
}
foreach my $t (@threads) {
$t->join();
}
