Program executes too slow to debug under gdb

Hello,

Can anyone offer some suggestions on how I can debug my application at a usable 
speed under gdb?  I`m using RedHat 6.2 on a 500mhz Dell Inspiron 7500 laptop, 
and have tried gdb 4.18 and 5.0, as well as other Linux distributions 
(several testers have reported the same problem too).  I`ve tried compiling with -

optimisation turned on, but with the same results - my app runs so slowly under 
gdb that its almost impossible to even select a menu item in less than 15 
minutes.  The only things I`m doing that might be considered the slightest bit 
unusual is calling a lot of functions, often recursively, to levels 40 or so 
deep, and using several linux threads.  If you would like an example, there is a -

.tgz archive of the app here:

Thanks in advance,
