Well, actually I can step inside kaffe.def from the function runVirtualMachine. But it just says "in kaffe.def: line n" without showing the C code that's getting executed. So that's what I meant in my earlier mail. Are you getting the same problem?

How did you get it to step into the kaffe.def file? I have been
trying to get that to work without success.
