Perl violates segmentation. Ooops. Perl 5.6.0\,RedHat Linux x86. Code that caused this was ment for mod_perl\, but has always passed syntax tests with -c\, or errored out with -e when the mod_perl request object was undefined. Additionally\, DBI\, Mail​::Sendmail\, LWP are used.

(notes about code that caused condition) The code that caused this condition is pretty involved. Lots of namespace minipulation and general Perl trickery. Spread accrost several modules. (Comprises our custom object framework and shoppingcart/category/admin etc). Debugging modules grab the warn and die SIG handlers. Most functions are generated from templates using lambdas. All functions are replaced with stubs that record evaluation path and use goto &$funcref to replace the original function in the stack frame.

"medium" priority because other people are unlikely to stumble upon this crasher ;)

Thank you for your hard work on Perl... Perl is da' bomb =)
