[kaffe] KAFFE_DEBUG set but doesn't enter into gdb

[ktlam at cs.hku.hk]

Dear all,

I want to debug kaffe. When I export KAFFE_DEBUG=gdb at command line and run 
my application script (in fact tomcat), it doesn't work. 
Although it shows the following: 

Copyright 2003 Free Software Foundation, Inc.

This GDB was configured as "i386-redhat-linux-gnu"...Using host libthread_db 
library "/lib/tls/libthread_db.so.1".

(gdb)

when I type 'r' to run, it prompts "command not found" and I think it hasn't 
really entered into gdb and stayed in the shell. 

I see the kaffe script in bin. It uses 'exec' which seems will not bring up a 
new process and just replace the program my telnet process is running. So 
should be no problem. Do you know what's wrong with me? Is this related to the 
underlying Linux platform?
 
Thanks a lot for attention. 

Tin
