</div>I can try that if anyone can help walk me through it or at least point me to<br>
a good beginner's tutorial for gdb. I never use commandline debuggers, and<br>
I've never even touched gdb, so I don't have the slightest clue how to use<br>
it.<br>

</blockquote></div>The short version is to run `gdb yourapp` which will get you into the GDB shell. Then `run` to actually start the app. It will halt and return to the shell when it hits the bad instruction, and you should type `disass` to view the assembly code of the current function. There will be a pointer (->, I think) pointing to the current instruction in the listing.<div>
You can find GDB basics at <a href="http://www.cs.cmu.edu/~gilpin/tutorial/">http://www.cs.cmu.edu/~gilpin/tutorial/</a> although that tutorial doesn't include `disass`. I mostly learned it by firing it up and typing `help` :D</div>
