Hi!The recent r244993 change where bypass_conditional_jumps is called only after splitting blocks for unconditional traps can result in ICEs during bypass_conditional_jumps, because on the (unreachable, to be removed later) new basic blocks created by that splitting we don't have cprop per-bb data structures like cprop_avout computed (nor space for them allocated). bypass_conditional_jumps already uses bypass_last_basic_block variable to avoid touching basic blocks created during that function, so this patch just extends that to also the basic blocks created for splitting after unconditional traps.

OK. jeff
