--- Comment #1 from vries at gcc dot gnu.org ---
For c.exp, at -Ofast/-g, this failure looks similar:
...
FAIL: libgomp.oacc-c/../libgomp.oacc-c-c++-common/reduction-1.c
-DACC_DEVICE_TYPE_host_nonshm=1 -DACC_MEM_SHARED=0 (internal compiler error)
FAIL: libgomp.oacc-c/../libgomp.oacc-c-c++-common/reduction-1.c
-DACC_DEVICE_TYPE_host_nonshm=1 -DACC_MEM_SHARED=0 (test for excess errors)
...
