[Bug libfortran/48915] New: Incorrect process return code with -fdump-core

           Summary: Incorrect process return code with -fdump-core
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: libfortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: jb@gcc.gnu.org


Consider the program

program errcode
  stop 10
end program errcode

$ gfortran errcode.f90
$ ./a.out 
STOP 10
$ echo $?
10
$ gfortran -fdump-core errcode.f90 
$ ./a.out 
STOP 10
Quit (core dumped)
$ echo $?
131

Looking at runtime/error.c (sys_exit) the reason is quite obvious; with 

kill(getpid(), SIGQUIT);

the process kills itself (return code is 128 + signal number = 131 in this
case) and never gets a chance to execute exit() with the provided exit code!

Assigning to myself, I have some ideas to improve error handling and fix this
in the process.
