Summary: gcc.dg/graphite/id-14.c ICEs with cloog-parma
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: howa...@nitro.med.uc.edu
Currently the gcc.dg/graphite/id-14.c test case causes an ICE when gcc trunk is
built against ppl 0.11 and the pre-release cloog-parma 0.16 at both -m32 and
-m64. This crash is of the form...
