That just exposed what previously ICEd I think.

I can see this with a cross to ppc64le as well, the pattern matches two tim=
es.
It's not clear to me what the testcase intends to test - it lacks a comment=
 :/

c3d2600cfb476^ also exhibits this problem, so does d2a898666609^ so this
problem must exist for longer time and it seems unrelated to this issue at
hand.  Can you properly bisect and open a different bugreport for this?=
