--- Comment #12 from Jeffrey A. Law <law at redhat dot com> ---
So the problem here is try_combine is playing things a bit fast and loose when
it rips apart the PARALLEL into two independent sets (one of which is a nop).
In particular it assumes that I3 is an INSN as opposed to a JUMP_INSN or
CALL_INSN. As a result combine is happy to create the bogus RTL as seen in
Andreas's last comment.
It's easily fixed and a patch for that is in testing.
