I am currently getting a segfault if I enable the exception handler. Running the code through -t, I see this near the end:
3844 set_eh P16 - P16=Exception_Handler=PMC(0x9e0518)
3846 find_lex P16, -1, S18 - P16=Exception_Handler=PMC(0x9e0518), , S18="a"
4094 print "excepted\n"
excepted
4096 set P2, P5["_invoke_cc"] - P2=NULL, P5=Exception=PMC(0x9e0500),
4100 invoke P2 - P2=RetContinuation=PMC(0x9e04e8)
3850 clear_eh
3851 print "HERE?\n"
HERE?
3853 typeof S17, P16 - S17="Sub", P16=NULL
4094 is the exception handler code - so that's getting called. It's a do nothing handler, so it just invokes back to where it was going, which it does.
I don't have a short example on this one - I can try to cook one up, if you like, but it may take a while.
The PIR associated with that is:
set_eh ignore find_lex lexical, -1, arg0 clear_eh print "HERE?\n" typeof type, lexical if type == "PerlUndef" goto no_such_variable
Here's the crash log (OS X)
