You need to use System.map to figure out what routine this crashed in.
You need a backtrace/stack dump
Then you need to create assembly for the file in question:
gcc -Wa,ah, -Wa,al
and figure out what the assembly was doing when it crashed. And then
read the source code to see why.
KDB makes this a *lot* easier.
