The following program uses an excessive amount of memory, which causes the
segmentation fault. valgrind shows:
==27188== Process terminating with default action of signal 11 (SIGSEGV):
dumping core
==27188== Access not within mapped region at address 0x7FE001700
==27188== at 0x427539: gfc_compare_derived_types (interface.c:365)
==27188== Invalid write of size 8

! The following works with 4.1.3 and 4.2.2, but fails
! (segmentation fault) with 4.3.0.
