--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
As a quick guess combine eventually doesn't honor non-call EH and combines
insns in a way that puts a trapping insn before another one.  Could also be a
x86 target specific pattern/splitter issue of course (not sure if passes are
supposed to split blocks - a splitter definitely can't).
