Created attachment 4775 [details]
tar file with ada source to reproduce bug 12318

* contains a directory "bug-12318" with the ada sources
* it seems to me that you have to split the input into several files - if I put
all ada source in a single package, the stuff can be compiled.

Oops, the command to produce the error:

go to the sources and type

Log message:
	2003-10-22  Arnaud Charlet  <charlet@act-europe.fr>
	
	* gnat_wrapper.adb: New file.
	
	2003/10/22  Jerome Roussel  <roussel@act-europe.fr>
	
	* g-regpat.ads, g-regpat.adb (Match): new function, to know if a
	string match a pre compiled regular expression (the corresponding
	version of the function working on a raw regular expression)
	Fix typos in various comments
	Update copyright notice in spec
	
	2003/10/21  Gary Dismukes  <dismukes@gnat.com>
	
	* exp_ch3.adb:
	(Component_Needs_Simple_Initialization): Return False when the type is a
	packed bit array. Revise spec comments to document this case.
	
	* exp_prag.adb:
	(Expand_Pragma_Import): Set any expression on the imported object to
	empty to avoid initializing imported objects (in particular this
	covers the case of zero-initialization of bit arrays).
	Update copyright notice.
	
	2003/10/21  Ed Schonberg  <schonberg@gnat.com>
	
	* sem_ch12.adb:
	(Load_Parent_Of_Generic): If parent is compilation unit, stop search,
	a subunit is missing.
	(Instantiate_Subprogram_Body): If body of function is missing, set type
	of return expression explicitly in dummy body, to prevent cascaded
	errors when a subunit is missing.
	Fixes PR 5677.
	
	* sem_ch3.adb:
	(Access_Subprogram_Declaration): Verify that return type is valid.
	Fixes PR 8693.
	
	* sem_elab.adb:
	(Check_Elab_Calls): Do not apply elaboration checks if the main unit is
	generic.
	Fixes PR 12318.
	
	* sem_util.adb:
	(Corresponding_Discriminant): If the scope of the discriminant is a
	private type without discriminant, use its full view.
	Fixes PR 8247.
