Here's the sample code:
http://lapcatsoftware.com/downloads/ConnectionStartCrash.m
It crashes when calling this:
_connection = [[NSURLConnection alloc] initWithRequest:request
delegate:self startImmediately:NO];
[_connection start];
but not this:
_connection = [[NSURLConnection alloc] initWithRequest:request
delegate:self startImmediately:YES];
Of course, you wouldn't normally want to call [_connection start]
immediately; in my tool, I was using performSelector:afterDelay: to
call it, and the crash still occurs.
Here's the backtrace:
#0 0x97092152 in CFSetApplyFunction ()
#1 0x95b0cdad in CFNSchedulingSetScheduleSource ()
#2 0x95b375bb in RunLoopMultiplexer::sourceForScheduling ()
#3 0x95b3769a in RunLoopMultiplexer::schedule ()
#4 0x95b88d96 in URLConnectionClient::start ()
#5 0x00001bd9 in -[MyConnectionDelegate connectWithCrash:]
(self=0x103330, _cmd=0x1f5c, shouldCrash=1 '\001') at /Users/jeff/

ConnectionStartCrash.m:24
#6 0x00001d38 in main (argc=1, argv=0xbffff694) at /Users/jeff/
Documents/Programming/TestProjects/ConnectionStartCrash/
ConnectionStartCrash.m:50
The argument for cachePolicy: doesn't seem to matter, by the way.
Am I missing something? Is there some run loop setup I need to perform?
