Bug ID: 59073
Summary: [4.9 Regression] ICE with missing increment in OpenMP
for-loop
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: reichelt at gcc dot gnu.org
The following invalid code snippet (compiled with "-fopenmp") triggers an ICE
on trunk:
==========================================
void foo()
{
int i;
#pragma omp distribute parallel for
for (i = 0; i < 10; i) ;
}
==========================================
bug.c: In function 'foo':
bug.c:5:23: error: invalid increment expression
for (i = 0; i < 10; i) ;
^
bug.c:4:9: internal compiler error: in gimplify_omp_for, at gimplify.c:6899
#pragma omp distribute parallel for
