Testcase:
#!perl
use POSIX q/sigaction/;
my $a1 = POSIX::SigAction->new( sub {} );
my $a2 = POSIX::SigAction->new();
sigaction(ALRM, $a1, $a2);
sigaction(ALRM, $a1, $a2);
sigaction(ALRM, $a2);
kill ALRM => $$;
__END__
This results in stack corruption on agricola (haven't tried on abel):
Program terminated with signal 11, Segmentation fault.
#0 0x41676952 in ?? ()
(gdb) bt
#0 0x41676952 in ?? ()
#1 0x41676952 in ?? ()
Backtrace stopped: previous frame identical to this frame (corrupt stack?)
