This is again:

2003-09-22  Olivier Hainque  <hainque@act-europe.fr>

	PR target/9786
	* reg-stack.c (convert_regs_1): Purge possible dead eh edges
	after potential deletion of trapping insn. Avoids later ICE
	from call to fixup_abnormal_edges.
	(convert_regs_2): Stack the current block successors before
	processing this block, that is, before the potential deletion of
	dead edges by convert_regs_1, because these edges have been used
	to initialize the predecessors count.


As I installed the patch, I'll investigate.
