I'm writing a test command-line tool that only uses Foundation. I want
to send a file to a server using HTTP PUT. The minimal code needed to
reproduce the problem is included at the bottom of this message.
When I run the program, I get an EXC_BAD_ACCESS with the following
stack trace
#0 0x9681177b in CFWriteStreamClose ()
#1 0x9636a8dc in spoolingClose ()
#2 0x9681157d in _CFStreamClose ()
#3 0x968da22f in closeRequestResources ()
#4 0x968d58c3 in httpConnectionStateChanged ()
#5 0x968f0f94 in sendStateChanged ()
#6 0x968f0f1e in _CFNetConnectionErrorOccurred ()
#7 0x968e220c in httpRequestPayloadCallBack ()
#8 0x9680f629 in _CFStreamSignalEventSynch ()
#9 0x967fd64e in CFRunLoopRunSpecific ()
#10 0x967fdd38 in CFRunLoopRunInMode ()
#11 0x96203560 in +[NSURLConnection(NSURLConnectionReallyInternal)
_resourceLoadLoop:] ()
#12 0x961a004d in -[NSThread main] ()
#13 0x9619fbf4 in __NSThread__main__ ()
#14 0x947de075 in _pthread_start ()
#15 0x947ddf32 in thread_start ()
The fault happens before my delegate receives a single message from
the NSURLConnection. Any suggestions as to what I'm doing wrong?
