The problem is that the freeze node of the type to which the real literal
is resolved is placed inside the expression function instead of outside.

gcc/ada/

	* freeze.adb (Freeze_Expression): Also attach pending freeze nodes
	to the parent in the case of an internal block in a spec expression.

Tested on x86_64-pc-linux-gnu, committed on master.
