           Summary: ABI for empty stop statement broken
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: jvdeli...@gcc.gnu.org


Prior to 4.6 a an empty STOP is translated into:

_gfortran_stop_numeric (-1);

The runtime looks for -1 as a signal for an empty STOP and just exist quietly.

However, this statement, if run inadvertently with the 4.6 library will not
exit quietly and will emit "STOP -1" with a -1 exit code. A -1 is a valid STOP
code with later Fortran standards.  I will post a proposed patch.
