Details:

I am running on an Intel NUC running debian wheezy, with hand built gnustep
1.24. My GCC is version 4.7.2.

This is sort of a corollary to this bug:
https://savannah.gnu.org/bugs/?func=detailitem&item_id=35686

I have written a wrapper around NSURLConnection called RPMHTTPConnection. In
the attached test program, I alloc/init an RPMHTTPConnection, send a request,
receive a callback, and then release the RPMHTTPConnection instance. However,
-dealloc is never called in my RPMHTTPConnection class and I suspect that the
underlying NSURLConnection is not releasing its delegate after the request
finishes. If I am more eager about releasing the NSURLConnection, like
releasing it in the method where RPMHTTPConnection calls its own delegate, the
dealloc is called as I would expect. 

Today, May 9th 2013, I checked out the latest gnustep and I do not see
_delegate being released after the connection finished or fails.

When I run the attached program I get this output:

NSURLConnectionBug[16514] got response from instance: 0x9b19e74, data length:
44074

When I run the equivalent program on my Mac I get this output:

NSURLConnectionBug[9650] got response from instance: 0x9d8e22c, data length:
44074
NSURLConnectionBug[9650] deallocing instance: 0x9d8e22c
