------- Comment #4 from belyshev at depni dot sinp dot msu dot ru 2007-09-14 19:15 -------
Very similar testcase with the difference that it is not fixed by r128415 and
makes current trunk segfault in VEC_tree_base_pop():
void f (unsigned int *d, unsigned int *s, int w)
{
int i;
for (i = 0; i < w; ++i)
d [i] = s [i] * (unsigned short) (~d [i] >> 24);
}
