In addition to FAQ.debugging, you should look at FAQ.xdebugging which
lets use see Java method names in C stack traces in GDB. You might
also look at the various macros in developers/gdbinit. In particular
'pobject' is probably useful.

Configure with --enable-debug. Then run with '-vmdebug ELOOKUP' to
see when exceptions are thrown and where they're caught.
Hope this helps,
