The bug is in

break;
}
When TREE_CODE (ii_tree) != ARRAY_NOTATION_REF:

it turns into an infinite loop.

Possibly related to: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61962
The reproducer attached to that bug (see below) also enters an infinite loop
(build with g++ -fcilkplus -c arrayinf.cpp):
struct FloatStruct
{
float *f;
};
/* Either SRC or DST must be a struct, otherwise the bug does not occur. */
void f (FloatStruct *dst, float *src, unsigned int length)
{
dst->f[0:length] = src[0:length];
}
