When I install and use an exception handler for the second time Parrot
dumps. It looks like the "set_eh" messes up the sub object in P10
because when I uncomment the second newsub it works...

Is this a behaviour of the hidden invoke (of the exception handler) that
I am unaware of?

.sub _main
		
	new_pad 0

	newsub P10, .Exception_Handler, _handler

	I12=1
	set_eh P10
	find_lex P13,"a"
	clear_eh
	P13=new PerlNum
	store_lex -1,"a",P13
	P13=I12
	find_lex P14,"a"
	print P14

	I17=2
	#newsub P10, .Exception_Handler, _handler
	set_eh P10
	print "mark1\n"
	find_lex P13,"b"	# <=== Crashes here
	print "mark2\n"
	clear_eh
	P18=new PerlNum
	store_lex -1,"b",P18
	P18=I17
	print P18
	end
.end

.sub _handler
        print "Hi from handler\n"
        set P2, P5["_invoke_cc"]
        invoke P2
.end
------------------------------------------------------------------------

When I run this code, "mark1" gets printed but then the interpreter
crashes:

------------------------------------------------------------------------
josv@jadzia:~/parrot/test >  ../parrot test9.pir 

Hi from handler
1mark1
Segmentation fault (core dumped)
