Subject: Crypt::RSA test 11 fails with a segmentation fault
Download (untitled) / with headers

I'm trying to compile Crypt::RSA on HP-UX.11.11 but the test number 11 (11-wrapper.t) fails with a segmentation fault: PERL_DL_NONLAZY=1 /vobs/prod/tools/perl/HP-UX.11/bin/perl "-MExtUtils::Command::MM" "-e" "test_harness(0, 'blib/lib', 'blib/arch')" t/*.t t/00-errorhandler....ok t/01-i2osp...........ok t/02-os2ip...........ok t/03-random_octet....ok t/04-octet_xor.......ok t/05-primitives......ok t/06-oaep............ok t/07-pss.............ok t/08-secretkey.......ok t/09-publickey.......ok t/10-keygen..........ok t/11-wrapper.........dubious Test returned status 0 (wstat 11, 0xb) DIED.

It seems that the expression '$self->{pp}->armour()' evaluates into an undefined value, thus causing a segmentation fault. Perl debugger claims that '$self->{pp}' is an empty hash. Another oddity is that sometimes I seem to get inside the 'armour' function, but the program dies in seg fault anyway.

This is likely a Math::PARI issue. Considering the bug was opened a long time ago, I'd really appreciate an update. I don't have access to an HP-UX box.
Closing this as a Math::Pari issue - likely resolved by now.

I ran in to this problem just recently. There is some conflict on HPUX between Math::Pari and Compress::Zlib, here's a trivial case # cat a.pl use Math::Pari; use Compress::Zlib; print STDERR "Here 1\n"; my $x=compress("zzzzz"); print STDERR "Here 2\n"; # perl a.pl Here 1 Bus error(coredump) # However, switch the two use statements around and... # cat a.pl use Compress::Zlib; use Math::Pari; print STDERR "Here 1\n"; my $x=compress("zzzzz"); print STDERR "Here 2\n"; # perl a.pl Here 1 Here 2 # ...it works. In the case of Crypt::RSA this manifests itself as a bus error in test 11 unless and until "use Convert::ASCII::Armour;" is moved above "use Crypt::RSA::Key;" and "use Crypt::RSA::Dataformat;". There's a before and after below - you can see the Bus Error goes away although we're still left with 'Decryption error' so it's not the only problem on this platform (for me anyway).
