[Bug fortran/25146] New: ICE on error diagnostics

["rep dot nop at aon dot at" <gcc-bugzilla at gcc dot gnu dot org>]

$ cat invalid_nullify.F 
       program ice_on_error_diagnostics
       implicit none
       TYPE (nonexisting_type1) t1 !, TARGET :: t1
       nullify(t1%something)
       end program
$ gfortran-4.0 invalid_nullify.F 
 In file invalid_nullify.F:3

       TYPE (nonexisting_type1) t1 !, TARGET :: t1                      
                              1
Error: Derived type 'nonexisting_type1' at (1) is being used before it is
defined
*** glibc detected *** free(): invalid pointer: 0x08510b00 ***

$ gfortran-4.0 --version
GNU Fortran 95 (GCC 4.0.2 (Debian 4.0.2-2))

I get the same ICE with gfortran-4.{1,2}

g77-3.4.5 does print the error diagnostics proper, so please set 19292 to
depend on this one.
