FWIW, I'm able to duplicate with an x86 cross to vax-ultrix. It looks as if
the problem lies here:
/* If store_expr stores a DECL whose DECL_RTL(exp) == TARGET,
but TARGET is not valid memory reference, TEMP will differ
from TARGET although it is really the same location. */
&& (TREE_CODE_CLASS (TREE_CODE (exp)) != 'd'
|| target != DECL_RTL_IF_SET (exp))
/* If there's nothing to copy, don't bother. Don't call expr_size
unless necessary, because some front-ends (C++) expr_size-hook
aborts on objects that are not supposed to be bit-copied or
bit-initialized. */
&& expr_size (exp) != const0_rtx)
