How large a file? It might be a memory management bug in pytables as  
well.

If you have the developer tools (Xcode & friends) installed you can  
find out where the crash occurs using gdb.

That is, 'gdb python', then on the prompt for gdb: 'r  
myscript.py' (adding arguments if needed). When the crash occurs you  
can use 'where 20' to see the topmost 20 frames on the C stack, or  
just 'where' to see the entire stack.
