Greetings, development people,
I'm trying to debug the problem I'm having where rosegarden crashes on loading
my autoload.rg.
I decided it was time to finally learn how to use gdb and its front-ends.
Well, I've been having problems, and for now, to simplify things, I cut out
the GUI front-ends and have been just trying to get debugging working with
gdb.
I seem to be getting different results running rosegarden directly (it
segfaults after setting up all the graphics and loading the autoload.rg),
then when running it under gdb, where it exits -1 much earlier, sometime
during the call to RosegardenApplication::start() in main().
So, classically, this is a symptom of some kind of memory corruption; however,
I'm so new at trying to use gdb that I think it is possible that instead, I'm
doing something wrong.
Thanks in advance for any hints about how my gdb setup could be wrong.
Regards
Larry Troxler
