[Bug fortran/27378] New: ICE on unexpected ELSE statement

[reichelt at gcc dot gnu dot org]

The following invalid testcase causes an ICE when compiled with -Wall:

===============
else
===============

The error message is:
 In file bug.f90:1

else
   1
Error: Unexpected ELSE statement at (1)
bug.f90:0: internal compiler error: Segmentation fault


Without -Wall I get:
 In file bug.f90:1

else
   1
Error: Unexpected ELSE statement at (1)
Error: Unexpected end of file in 'bug.f90'

This happens since GCC 4.0.1.
