Confirmed, the problem is:
/* If this expression has side effects, show we don't know it to be a
constant. Likewise if it's a pointer or aggregate type since in
those case we only want literals, since those are only optimized
when generating RTL, not later.
And finally, if we are compiling an initializer, not code, we
need to return a definite result now; there's not going to be any
more optimization done. */
if (TREE_SIDE_EFFECTS (arglist)
|| AGGREGATE_TYPE_P (TREE_TYPE (arglist))
|| POINTER_TYPE_P (TREE_TYPE (arglist))
|| cfun == 0)
return integer_zero_node;
I don't know much about anything else but a work around is using a variable to
store the results (yes this is stupid and it should not dependent on that).
