Now that the really baad OpenMP bugs seem to be fixed (thanhsk for that!) I
have a hopefully easy one: I get an ICE (svn from today) for the following C
code (and the C++ equivalent as well):
void f()
{
unsigned int i;
int dummy;
#pragma omp parallel for
for (i = 0; i < 5; ++i)
dummy = i;
}
LANG=C gcc-4.2 -c -fopenmp -o gcc-bug-signed.o gcc-bug-signed.c
gcc-bug-signed.c: In function 'f':
gcc-bug-signed.c:6: warning: iteration variable 'i' is unsigned
gcc-bug-signed.c:6: internal compiler error: in gimplify_omp_for, at
gimplify.c:4753
FYI icc 8.1 flags the unsigned variable as error.
