            Bug ID: 66707
           Summary: Endless compilation on wrong usage of common
           Product: gcc
           Version: 5.1.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gerhard.steinmetz.fortran@t-online.de
  Target Milestone: ---

After printing some correct and helpful error messages,
compilation of the following snippets (wrong code) will not end.
Tested with gfortran 5.1.1, 4.9.0, 4.8.3 (on SUSE Linux 13.2, 64 bit).


$ cat zlctc_1.f90
program p
   c = 1
   common // c
   common // c
end


$ cat zlctc_2.f90
program p
   integer, pointer :: a
   common a, a
   common a
end


$ cat zlctc_3.f90
program p
   integer, pointer :: a
   common a => null()
   common a => null()
end


$ time gfortran zlctc_1.f90
zlctc_1.f90:3.14:

   common // c
              1
Error: Unexpected COMMON statement at (1)
zlctc_1.f90:4.14:

   common // c
              1
Error: Unexpected COMMON statement at (1)

--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
Confirmed with 4.9.3 and 5.2. This seems to have been fixed on trunk between
revision r226476 (2015-08-02, endless compilation) and r227016 (2015-08-19,
tests compiled in a fraction of second).
