Interpreting perl stackdump

[MgFrobozz]

I'm getting a perl stackdump when I run code created by swig-1.3.27. How do I figure out what functions are represented?

Exception: STATUS_ACCESS_VIOLATION at eip=00B5137A

without relavant lines in the executable, we're gonna have it hard on this one ... what else have you loaded?

Please rephrase the question ;-) Puhlease ;-)

Hi, PaulTEG ...

The problem is that I don't know which lines are relevant, because I haven't a clue where the crash is occurring. I need something like a symbol table, but I don't know enough about perl to know how to get one.

I'm beginning to suspect that the problem is related to the use of two dll's by the program. One is originated by msdev, the other is originaled by swig (using gcc).

I'm also wondering whether an error that I got when configuring Win32::API may be related to this problem; is there any easy way to correct the perl and config.pm mismatch? Does the second entry indicate that config.pm thinks I'm running on a 64-bit processor?


> perl Makefile.PL
Have /lib/perl5/5.8/cygwin/Config.pm expected /usr/lib/perl5/5.8/cygwin/Config.pm
Your perl and your Config.pm seem to have different ideas about the
architecture they are running on.
Perl thinks: [cygwin]
Config says: [cygwin-thread-multi-64int]
This may or may not cause problems. Please check your installation of perl
if you have problems building this extension.

cygwin, looks like a few personalities ...

Aside from that, to be sure, if we*(as in me) had the time, more code might help ... and a token/symbol table ... the source and expectation, well they'd be welcome too.
