/opt/gcc/gcc-4.4-work/gcc/testsuite/gfortran.dg/alloc_comp_constructor_1.f90:
In function 'test_constructor':

internal compiler error: in operand_subword, at emit-rtl.c:1364
I don't see this ICE on i686-apple-darwin9. Note that
alloc_comp_constructor_1.f90 gives other failures related to pr38324.
The backtrace before the ICE gives:
