  16 # Test GDB can cope with Fortran strings having their length present in a CPU
  17 # register.  With -O0 the string length is passed on the stack.  To make this
  18 # test meaningful the follow assertion should pass.  It is not being checked
  19 # here as the "_s" symbol is compiler dependent:
  20 #   (gdb) info address _s
  21 #   Symbol "_s" is a variable in register XX.
