Compiling the following invalid testcase with -fopenmp causes an ICE:
===================================
void foo()
{
#pragma omp parallel for
for ( i=0; i<1; ++i ) ;
}
===================================
bug.c: In function 'foo':
bug.c:4: error: 'i' undeclared (first use in this function)
bug.c:4: error: (Each undeclared identifier is reported only once
bug.c:4: error: for each function it appears in.)
bug.c:4: error: invalid type for iteration variable '<erroneous-expression>'
bug.c:4: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in c_finish_omp_for, at c-omp.c:210
Please submit a full bug report, [etc.]
