I see the same on Fedora 11.  The -E expansion of the line in question is
  subref = Perl_newRV(((PerlInterpreter *)pthread_getspecific((*Perl_Gthr_key_ptr(((void *)0))))),
(SV*)((((GV*)sub_glob)->sv_u.svu_gp)->gp_cvgen? ((void *)0) : (((GV*)sub_glob)->sv_u.svu_gp)->gp_cv));
 

so it's evidently unhappy about the fact that GvCVu can return null,
while Perl_newRV is declared __attribute__((nonnull(2))).

It looks to me like this is probably a live bug not just compiler
hypersensitivity.
