           Summary: ptr & 0 not considered as constant
           Product: clang
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2

the following code is rejected by clang (with "initializer element is not a
compile-time constant"):

struct sym_reg {
        char nc_gpreg;
};

int sym_fw1a_scr[] = {
           ((int)(&((struct sym_reg *)0)->nc_gpreg)) & 0
};
