gcc/testsuite/gfortran.dg/used_dummy_types_2.f90

   1 ! { dg-do compile }
   2 ! This tests that the fix for PR25391 also fixes PR20244. If
   3 ! the USE mod1 in subroutine foo were deleted, the code would
   4 ! compile fine.  With the USE statement, the compiler would
   5 ! make new TYPEs for T1 and T2 and bomb out in fold-convert.
   6 ! This is a slightly more elaborate test than
   7 ! used_dummy_types_1.f90 and came from the PR.
