Perhaps phrack article in issue 58 file 03 could help you :) In case
you're lazy, here's the URL:

http://www.phrack.org/issues.html?issue=58&id=3#article

look for the section:
"Subject: Getting rid of SIGSEGV - for fun but not for profit."

A bit hackish, but I think it is worth to read. Enjoy :)
