Take the following example:
static const char f[3] = "?";
int main(void)
{
if (f[0] == '?')
abort ();
return 0;
}
We don't optitimize this at the tree level.

This is just like PR 14841 but that one is already fixed.
Kazu could you comment on this since you fixed the other bug?

I should note this was reduced from gcc.c-torture/execute/20000227-1.c and was pointed to me by
