3 ! Test the fix for PR78990 in which the scalarization of the assignment
4 ! in the main program failed for two reasons: (i) The conversion of 'v1'
5 ! into a class actual was being done after the call to 'return_t1', giving
6 ! rise to the ICE reported in comment #1; and (ii) The 'info' descriptor,
7 ! required for scalarization was not set, which gave rise to the ICE noted
8 ! by the contributor.
