Package: gnat-4.6
Version: 4.6.3-2
Severity: normal

Hi,

Exceptions with tracebacks enabled (gnatbind -E switch) cause a
STORAGE_ERROR on kfreebsd-i386 when raised in a task rendezvous.

Simple reproducer:

procedure Main
is
   task Test_Task is
      entry Rendezvous;
   end Test_Task;

   task body Test_Task is
   begin
      accept Rendezvous do
         raise Constraint_Error with "Some error occurred";
      end Rendezvous;
   end Test_Task;
begin
   Test_Task.Rendezvous;
end Main;

This code works fine without tracebacks in exception occurrences. Enabling tracebacks:

package Binder is
   for Default_Switches ("ada") use ("-E");
end Binder;

This produces the following result:

Execution terminated by unhandled exception
Exception name: STORAGE_ERROR
Message: s-intman.adb:139 explicit raise
Call stack traceback locations:
0x2808c27b

gdb backtrace:

The signal ? looks suspicious, but I'm not sure if this is another problem on this arch.

Regards,
