gcc-4.1-200506011 compiler ICE's using -ftree-vectorize AND
-fdump-tree-all-details-stats in conjunction. Leave out one of both
options and you got a successful compilation.


Command:

/opt/gcc-4.1-20050611/bin/gcc -O3 -march=pentium4 -msse3 -save-temps
test.c -o test -ftree-vectorize -ftree-vectorizer-verbose=5
-fdump-tree-all-details-stats

Error message:

test.c: In function 'main':
test.c:2: internal compiler error: in op_iter_init_maydef, at
tree-flow-inline.h:1065
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

Source Code (I wrote a stupid little program to reproduce the error):

int main(void)
{
    int a[1024];
    int b[1024];
    
    int c[1024];
    
    int i, j = 0;
    
    for (i = 0; i < 1024; i++) {
	a[i] = i;
	b[i] = 1023 - i;
    }

    for (i = 0; i < 1024; i++)
	c[i] = a[i] + b[i];

    for (i = 0; i < 1024; i++)
	j = j + c[i];
	
    return j;
}

    for (i = 0; i < 1024; i++) {
 a[i] = i;
 b[i] = 1023 - i;
    }

    for (i = 0; i < 1024; i++)
 c[i] = a[i] + b[i];

    for (i = 0; i < 1024; i++)
 j = j + c[i];

    return j;
}
