2! Test the fix for PR38863, in which an unnecessary temporary
3! generated results that are not consistent with other compilers.

36! The problem occurred here: gfortran was producing a temporary for these
37! assignments because the dependency checking was too restrictive.  Since
38! a temporary was used, the integer component was reset in the first assignment
39! rather than being carried over.
