! Tests the fix for PR41478, in which double frees would occur because
3 
! transformational intrinsics did not copy the allocatable components
4 
! so that they were (sometimes) freed twice on exit.  In addition,
5 
! The original allocatable components of a1 were not freed, so that
6 
! memory leakage occurred.
