--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
I was thinking of sth else first - make sure that points-to analysis processes
initializers of readonly globals (when they bind to the current def).  In
your testcase the globals are not readonly - or did you mean to write

int * const varptr = &var;
int * const __restrict__ varptr2 = &var;

?  Your testcase also misses a declaration of 'var'.
