exception handling

I have a Perl module that calls a function from in a Swig generated 
module, which in turn calls a function in a shared library. It's been a 
while since I put it all together and made it work, so I'm kind of hazy 
on the technical details - and since it mostly works I never need to 
look at it.

There is occasion, when called with incorrect parameters, that the 
wrapped function(s) will create a segmentation fault. I'd like to be 
able to get the details of the seg fault up to the Perl/CGI script that 
runs all of this. Is there some way I should be wrapping calls to the 
shared lib in something like an eval BLOCK, so I can croak a message 
back to the web page?

Thanks!
