Bug ID: 65576
Summary: ICE in gcc.c-torture/compile/pr33855.c
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: msebor at gcc dot gnu.org
Compiling the gcc.c-torture/compile/pr33855.c test with yesterday's trunk
(r221640) on powerpc64 (a POWER7 processor) fails with the ICE below. Adding
#include <complex.h> doesn't help. I don't see this ICE on powerpc64le.
