The following code segfaults GCC 4.5 (and GCC trunk 159536) when compiled with
:
$ gcc -O1 -floop-parallelize-all test-17.c
Program received signal SIGSEGV, Segmentation fault.
0x00007ffff7bce389 in cloog_domain_stride (domain=<value optimized out>,
strided_level=<value optimized out>, nb_par=<value optimized out>,
stride=<value optimized out>, offset=<value optimized out>) at
source/ppl/domain.c:2813
2813 cloog_vector_gcd (U->p[0], U->NbColumns, stride);
GCC built with : cloog-ppl-0.15.9 ; gmp-4.3.2 ; mpc-0.8.1 ; mpfr-2.4.2 ;
ppl-0.10.2
The crash seems to be very specific to this value of N.
#define N 4
int A[N][N][N];
void
kernel ( void )
{
unsigned int i, j, k;
for ( i=0; i<N; ++i )
{
for ( j=0; j<N; ++j )
{
for ( k=0; k<N; ++k )
{
if ( i == j )
{
if ( (k+1) == j )
A[i][j][k] = 1;
else
A[i][j][k] = k;
}
else
{
if ( (i+1) == k )
A[i][j][k] = j;
A[i][j][k] += 3;
}
}
}
}
}
