Subject: Attempt to free unreferenced scalar when used with Package::Stash
Download (untitled) / with headers
text/plain 821b
Perl is throwing a "free unreferenced scalar" error when pairmap is used in conjunction with Package::Stash (0.36). I'm not sure which package is at fault, but the error is thrown at a line number after the pairgrep invocation (not within it), so I'm guessing(!) it might by Package::Stash. Here's the failing code: use Package::Stash; use List::Util 'pairmap'; my $m = Package::Stash->new('main'); my %h = ( a => 1, b => 2 ); pairmap { $m->add_symbol( '$'. $a, $b ) } %h; print $a; and here are the results when run under either 5.16.3 or 5.20.0: Attempt to free unreferenced scalar: SV 0x13bc5e0, Perl interpreter: 0x1347010 at t1.pl line 14. Attempt to free unreferenced scalar: SV 0x1368f18, Perl interpreter: 0x1347010. A simple loop over the hash rather than using pairmap works fine. Thanks, Diab
