David,
I have seen one other bug that looks something like this. From the
backtrace you attached to the bug, it looks like there is some cycle in
class hierarchy as represented in the debug info for your app. gdb
crashes trying to figure out whether some field is a member of a class.
The crash comes because it has blown out the stack recursing through
baseclasses of the original class. I doubt you actually have a class
hierarchy that is some thousands of levels deep. So there is either
some bug in the debug info, or in gdb's reading thereof.
To figure this out, I need to look at a copy of your app (with debug
info) or some simpler example that shows the same problem. I only need
the executable with debug info, not the source or the Xcode project or
anything like that. If you can get me this and tell me some place
where I can set a breakpoint to see the crash, I can most likely figure
out what is going on.
Thanks,
Jim

I've got a C++ (Carbon) application which I used to be able to debug,

if I set one in the window class, the debugger always crashes when it
hits the breakpoint.
I've tried removing Xcode preferences, removing my build folder,
reinstalling Xcode.
I've filed a bug in Radar. But I wonder if anyone knows of another
GDB-related cache or preference that I can delete.
