There should be more information in the Xcode-gdb log, which you can turn on in the Debugger Pane of the Xcode Preferences. If you want to chase this down further, please turn on this logging, run a session that mysteriously stops like this, and then grab the log and file a Radar including the log and a description of how you are running your program.

It looks like this is the relevant message:

<- 208*stopped,time= {wallclock = "13.34395 ",user = "0.63998 ",system = "0.35733 ",start="1232038718.821371",end="1232038732.165319"},reason="signal- received",signal-name="SIGTRAP",signal-meaning="Trace/breakpoint trap",thread-id="1"

Does this mean that it thinks it hit a breakpoint? I can submit the whole project in a bug report, but it requires a PostgreSQL database (network connected) with a specific schema and data set. Please advise.

The low-level routine __NSI0 in NSInvocation switches off of the argument information. If the information is inconsistent or corrupted, the default case in the switch statement executes a HALT. That's what you're hitting; you are not providing the correct arguments to NSInvocation.
