Migration of Gui4Cli to OS4 Dbg questions

Hi,
the migration of D. Keletsekis Gui4Cli to OS4 is progressing well.
For now it is allready much more stable on my SAM than the 68k version.
The presence of the gdb debugger in the SDK was one of the factors that convinced me the job would not be beyond my possibilities.

It did not help a bit till the source compiled though, and after that i was rather disappointed. I was never able to use breakpoints as a substitute to debugprint statements in the source.
I expected the 'source' command to be usefull,(having a number of petentially usefull breaks in one document), but i never saw more than the first break. using 'continue', 'step' or 'next' was rather impredicatable.
When having a crash, the stacklog proved to be very usefull, but the rest remained chinese to me. Trying to attach GDB after a crash generally resulted in gdb freezing and or in a general freeze.
As i would like to port Gcview (a Gui4Cli addon for picture manipulation) as well, i would like to hear more about your experience with gdb.
Can you make more out of it?
