Crypt::RSA tests fail with a segfault

[Jussi Mononen]

Hi,

I'm trying to compile Net::SFTP for HP-UX.11 and everything else is a
success but Crypt::RSA. All required modules compile without problems,
but RSA tests fail with a segmentation fault.

I am able to compile Net::SFTP without the support for RSA Public Key
Authentication but unfortunately I would need RSA pub key auth.

Here is a printout from the failing test '11-wrapper.t'

Segmentation fault

--

In addition the test process seems to reserve every bit of CPU time it
can according to 'top' and it will freeze the perl debugger if used.
I've managed to find out that the problem is in '$rsa->encrypt'
function call. With the debugger I can get really deep by
step-by-stepping into it without any success of finding out where the
problem might be. I had no problems with Crypt::RSA on Solaris.

Sometimes instead of sigfault I get bus error. Am I running out of
system resources?

My perl is compile using the HP C compiler. DO you find anything new
what may cause the problem. I already build this module before with
an old version of perl but try to compile a new perl bundle and got
that... This module has too many dependency maybe some of then cause
the problem (?! suspect Math::Pari which is a weird module).

Ciao

I've found something, though I haven't solved this yet. It seems that
the process dies with segmentation fault when invoking
'$self->{pp}->armour()' -function in 'RSA.pm' line 109 (from
Convert::ASCII::Armour module)

If you change the armour flag to zero (eg. Armour => 0) in the
function call to '$rsa->encrypt' in '11-wrapper.t' -file the test will
go smoothly. But it still leaves us with the problem that cyphertext
can not be armoured...

Still quoting myself ;-)

with the help of perl debugger I made a surprising discovery. It seems
that the expression '$self->{pp}->armour()' evaluates into an
undefined value, thus causing a segmentation fault. You can not call
an undefined function can you? Perl debugger claims that '$self->{pp}'
is an empty hash...
