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