Timed out fetching data. Variable display may be inaccurate.
Although I get no errors at compile time - and no errors if just 'build
& run' - when stepping thru my code, the console receives many messages
such as shown above - and the 'step-over' time is in the 5 to 10-second
range. At some point an "Unable to disassemble ??. Program received
signal: "EXC_BAD_ACCESS"." msg appears and the game is over.
I guess the perplexing thing is that I don't seem to be doing anything
(at the time) that would tend to generate such a message. For
instance,
OSErr err = [mDsrc acquireList:sectionSubDefDict];
generates these lines into the console:
2004-07-22 09:10:47.708 TestApp[1089] *** -[TestAppMain length]:
selector not recognized
2004-07-22 09:10:47.717 TestApp[1089] *** -[TestAppMain length]:
selector not recognized
Other messages, such as below, appear in response to code such as:
if((NULL != (void*)myDictionary) && (NULL != (void*)myString)) //
don't access garbage
{
...
}
2004-07-22 09:13:13.400 TestApp[1089] *** -[NSCFString count]: selector
not recognized
2004-07-22 09:16:35.466 TestApp[1089] *** -[NSCFDictionary length]:
selector not recognized
Evidently, this whole issue is most problematic with 10.2.8 targeted
executables. The 10.3 world does not seem to suffer any ill effects
from all of this - on occcasion, the 10.2 SDK generated executables
that are not reliable, consistent or deterministic - depending on your
favorite vocabulary for such anomalies.
Any thoughts on how best to move away from this badness?
Thanks,
Lance Drake
