gdb woes

gdb woes

[Guillaume Dargaud]

Hello all,
I have some trouble when trying to use gdb to debug a custom app.
That app crashes for no reason but always on the same spots (probably 
hardware related, it runs on homebrew ppc-based card).
I've used gdb in the past, but always as part of 'bigger' IDEs.

So I run "gdb myapp" locally on the card and I get the prompt. Then I "run" 
it and I get dumped back to bash, but a "ps" shows that the app is still 
running... Anybody has a clue to what I can do about this ? Is there 
something wrong with my gdb (it's compiled as part of buildroot, like the 
rest of the OS) ?

If you can reduce your problem to a simple test case that others can
reproduce, it will be easier for others to look at your issue.  

If you think it's a problem with GDB, you might want to send this
message to an appropriate GDB list here:
