You can try something like "printf "%s\n", target->name->data" from within gdb
to get the name of the class. As an alternative you can add some debugging code
to the function to print out the name of the class and other data in the event
something unexpected happens (such as a depth == 0 class that is not caught by
one of the conditions).
As Jeff said, you should also rebuild libgcj with "CCFLAGS = "-O0 -g"" when
doing this sort of debugging to avoid seeing confusing behavior from gdb due to
optimizations.
