[Bug ada/15803] New: Illegal program not detected, RM 8.3(19)

[ludovic dot brenta at insalien dot org]

(Debian bug #246385)

package Test_246385 is
   type acc_p is private;
private
   type acc_p is access procedure
      (x: acc_p);  --ERROR: acc_p not visible until end of declaration
end Test_246385;


I expect an error message such as:
test_246385.ads:5:10: "acc_p" not visible until end of declaration, RM 8.3(19)

But the compiler says naught.

Sure, I understand. Actually it was more than reformatting, we changed the
error message also and a few other things.

But you definitely deserve to get your name as well on this patch, now added.

Arnaud,

for traceability purpose, I would appreciate to be credited in the ChangeLog as
well for this change as I am the one who submitted the patch for sem_ch3.adb
(Check_For_Premature_Usage procedure and Access_Subprogram_Declaration change)
that you committed (after some reformatting).

        PR ada/15803, ada/15805
        * sem_ch6.adb, sem_ch3.adb (Constrain_Access): In Ada2005, diagnose
        illegal access subtypes when there is a constrained partial view.
        (Check_For_Premature_Usage): New procedure inside
        Access_Subprogram_Declaration for checking that an access-to-subprogram
        type doesn't reference its own name within any formal parameters or
        result type (including within nested anonymous access types).
        (Access_Subprogram_Declaration): Add call to Check_For_Premature_Usage.
        (Sem_Ch3.Analyze_Object_Declaration, Sem_ch6.Process_Formals): if the
        context is an access_to_variable, the expression cannot be an
        access_to_constant.

Thanks for reopening it Ludovic. Yes, I mixed up the PR#, I'll fix the
ChangeLog and close the right one. It's been two times this week, I guess it's
bad for my health to go through so many Ada PR at a time :)

Samuel, this PR is not about variant parts.  I think you closed the wrong bug.
