If you want to compile kaffe for interpreter mode, the
easiest way to do it is to configure it with the
interpreter engine. Run ./configure --help in kaffe
source directory for more information on how to do it.

You should also configure kaffe with debugging
enabled. Then run your program with the option
-vmdebug list to see what debugging options are
available. In your case I recommend taking a look at
the INT_* options, like  INT_INSTR.

If your program is crashing somewhere, then running
kaffe a debugger is a much better way to find out what
is going on. Read FAQ/FAQ.debugging and
developers/gdbinit

Hope this helps,
