[Bug middle-end/40157] New: [4.4 Regression] ICE with -floop-block

[arthur dot loiret at gmail dot com]

Hi,

With this simple testcase:

int buffer[256*256];
int main(void)
{
    int *dest = buffer;
    int x, y;
    for(x = 0; x < 256; x++)
        for(y = 0; y < 256; y++)
            *dest++ = 0;
    return 0;
}

We get an ICE:

% gcc-4.4 -O1 -floop-block foo.c -o foo
foo.c: In function ‘main’:
foo.c:2: internal compiler error: in expand_scalar_variables_expr, at
graphite.c:4295
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.4/README.Bugs> for instructions.


Thanks.
