I have a fairly unusual yet very annoying problem.
Sometimes when debugging my app, I'll be stopped in the Xcode debugger
investigating some code. Not frequently, but often enough, the
debugger will stop responding to my attempts to twiddle disclosure
triangles to see variables. If I wait long enough, eventually I get a
system crash dialog noting an exception of type EXC_BREAKPOINT.
Needless to say, my debugging session ends. ;-)
A separate, but possibly related, issue is that sometimes when
enabling or disabling breakpoints, my app will spontaneously quit, and
Xcode will note that it exited with the result 1. No crash dialog
results in this case. So now I'm leery of enabling/disabling
breakpoints while debugging.
More background info: I'm debugging a 32-bit Intel-only Mac app that
is heavily C++ based. I've seen this happen on both a gimpy iMac Core
Duo 1.8 GHz and a early 2008 quad-core Mac Pro, both with 10.6.1/Xcode
3.2/gcc 4.0. There are roughly 1100 .cpp source files in this project.
This is not reproducible with any regularity. What can I do to help
track this down?
For the moment I have enough hair that I can afford to keep pulling it
out, but it's becoming a limited resource. ;-)
