can you provide some more information?  The crash.dmp file perhaps (please generate a fresh one so it contains only one or two crashes).  Can you also possible boy disassemble the trampoline table to see what code is generated for s stack switch?  Any of the send trampolines will do.  To do this, in gdb put s breakpoint in interpret, run and proceed once, then call printTrampolineTable(), and then disassemble a send routine using a pair of addresses from the output.

AdvThanksance
