   2 ! This tests the fix for PR24866 in which the reference to the external str, in
   3 ! sub_module, would get mixed up with the module procedure, str, thus
   4 ! causing an ICE.  This is a completed version of the reporter's testcase; ie
   5 ! it adds a main program and working subroutines to allow a check for
   6 ! correct functioning.
