[Bug c/14256] New: Vector extensions cause internal compiler error

["bmerry at cs dot uct dot ac dot za" <gcc-bugzilla at gcc dot gnu dot org>]

The following simple program produces the following error message. I include the
unpreprocessed source code since no header files are used. The machine is an
Athlon Thunderbird, although no -march or -mcpu arguments were given. Removing
the bogus function call makes the problem go away.

bmerry@goldfish:~/tmp$ gcc-3.3 -c internal.c 
internal.c: In function `main':
internal.c:4: internal compiler error: in ix86_function_arg_boundary, at
config/i386/i386.c:2422
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

int main()
{
    int f __attribute__ ((mode(V4SI)));
    cheddar(f);
}
