Package: perl
Version: 5.32.1-4+deb11u2
Severity: normal
I've done a Ctrl-C to terminate a Perl script. But it was terminated
with a segmentation fault:
[...]
Reading tmp/tst-arbre-1698058266-44878-8.results ...
^CInterrupt

The script has
$SIG{'INT'} = sub
{ maplepid and quitmaple;
$SIG{'PIPE'} = 'DEFAULT';
warn "Interrupt\n";
exit; };
I'm seeing the "Interrupt" above.
