* sem_ch4.adb (Analyze_Expression_With_Actions.Check_Action_Ok):
If Comes_From_Source (A) is False, then look at Original_Node (A)
instead of A. In particular, if an (illegal) expression function
is transformed into a "vanilla" function, we don't want to allow
it just because Comes_From_Source is now False.
Tested on x86_64-pc-linux-gnu, committed on master.
