Compile with -g and run the program under GDB.  I think GDB will tell
you where did the exception happen even if you just run it (without
single-stepping or breakpoints), because GDB gets the exceptions of the
debuggee.  If I'm wrong, you'll have to single-step through the
function(s) that you suspect until you find the line that triggers the
exception.
