Stack Smashing is actually a protection mechanism used by gcc to detect
buffer overflow attacks.
You can disable this protection of gcc using option
-fno-stack-protector
while compiling Perl.
see: http://stackoverflow.com/questions/1345670/stack-smashing-detected
assp.pl could not cause this stack attack - because it is not handling any
stack it self - Perl and the XS components of the loaded modules are
handling the stack. I think any of the used modules is causing this in its
XS (C or c++) code.

Betreff:[Assp-test] 2.3.3 keeps crashing
I saw yesterday that someone else had the same problem. I managed to
capture a traceback (below) - hopefully that helps diagnose the problems.
