[Bug fortran/44371] New: [4.6 Regression] STOP parsing rejects valid code

There, Al Greynolds reports that the following program fails to compile with:

  if (c=='y') stop; if (c=='Y') stop
                   1
Error: Syntax error in STOP statement at (1)


I assume it is due to the new expression parsing for (ALL) STOP, which gets
confused if no expression is matched because of a semicolon rather than because
of EOL.


  character(1) c
  read(*,*) c
  if (c=='y') stop; if (c=='Y') stop
  end
