This happens when the discriminants of the record type have default values.

gcc/ada/ChangeLog:

	* inline.adb (Expand_Inlined_Call): In the case of a function call
	that returns an unconstrained type and initializes an object, set
	the No_Initialization flag on the new declaration of the object.

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