After running into this issue for the 10 billionth time and nearly whipping my mac air out the window in frustration, I've decided to break down and ask if anyone else has run into this...
Environment: running the latest version of XCode (as of this question: 4.2, build 4C199) for an iOS 4.2+ application (universal app).
It appears that GDB randomly decides to completely hang while stepping through lines of code. This has happened to me now on multiple codebases, and in various locations throughout each codebase. The stepping process hangs on an arbitrary point and requires that the running iOS simulator or on-device process be stopped and restarted. Typically, after restarting my debugging session I am able to get to a different arbitrary point in stepping into/thru -- sometimes even enough to actually debug my code entirely (gasp).
I tried wiping my drive, re-installing a fresh copy of Mac OS X 10.6.8 and the aforementioned XCode... No difference.
I tried switching debuggers to LLDB; this resolved the hanging issue, but I'm not as big a fan of LLDB and prefer to use my environment as close to stock as possible.
Any thoughts?
