PowerPC Ada program terminates with internal error (on psim)

[avy st]

Hello All,

  I just completed a what I hope is a successful build of a Cygwin based Ada supporing toolset (based on gcc-4.1.20060909 snapshot) for PowerPC, and RTEMS 4.6.99.3, psim and ss555 BSP.

  However, when running a simple Ada 'hello' test program, the program runs correctly, and then RTEMS complains about an internal error.  Here is a gdb log that shows the problem (psim BSP):

Hello RTEMS Ada

(gdb) quit
The program is running.  Exit anyway? (y or n) 

The Ada test program is:

with Ada.Text_io;
procedure T is
begin
  Ada.Text_IO.Put_Line("Hello RTEMS Ada");
end T;
The C hello test progam shows the 'normal, expected' behavior:

Any Ideas?
