gdb internal error

Hello,
I am new to Ada and I am following the tutorial of gps. I am on a 
red-hat 9 ix86 PC.
When trying the section "Debug", I had the following message in the 
debugger console:

file /users/mpup371/ada/tutorial/obj/sdc
(gdb)
internal error - unimplemented function unk_lang_create_fundamental_type 
called.
(gdb) run input.txt

Program exited normally.
(gdb)

and in debugger execution:

Welcome to sdc. Go ahead type your commands ...
1 2 + print
*** Internal Error *** : Please report it.




Is it the right place to submit this problem ?

Thx for your help,

jf
