* [Bug tree-optimization/18425] New: ICE in vector.tcc when -ftree-vectorize enabled

I reduced the problem to a small, albeit nonsensical, test case:
#include <vector>
void foo() {
std::vector<char *> v;
while (1)
v.resize(1);
}
I'm compiling with -O3 -ftree-vectorize -march=pentium4 on gcc 4.0.0(20041110).
I think this is related to bug 18397, but since it's unconfirmed I figured it
may help to have another case.

Confirmed, reduced all the way down to:
char ** _M_allocate();
void
_M_fill_insert(unsigned int __n)
{
char **__new_start = _M_allocate();
char *__tmp = 0;
for (; __n > 0; --__n, ++__new_start)
*__new_start = __tmp;
}
