Should have been fixed by ensuring _GNU_SOURCE is not defined.
Please try it.

Hope it behaves as it should.

[bug #35686] NSURLConnection does not retain its delegate (compatibility issue)

URL:
  <http://savannah.gnu.org/bugs/?35686>

                 Summary: NSURLConnection does not retain its delegate

    _______________________________________________________

Details:

On OS X and iOS, "NSURLConnection retains its delegate when it is initialized.
It releases the delegate when the connection finishes loading, fails, or is
canceled." (From the NSURLConnection class reference overview.) This means the
application does not have to explicitly retain or release the delegate object
as long as it's an ephemeral object specific to that request (which is pretty
common.)

On GNUstep, however, this doesn't happen.  This is very likely to lead to
incorrect behavior, most likely the app crashing when the NSURLConnection

[bug #35699] NSStrings can point into garbage memory (misuse of app-supplied backing buffer)

URL:
  <http://savannah.gnu.org/bugs/?35699>

                 Summary: NSStrings can point into garbage memory (misuse of
app-supplied backing buffer)
                 Project: GNUstep
            Submitted by: snej

    _______________________________________________________

Details:

NSString is insufficiently careful in its use of externally-provided buffers
(i.e. passed to -initWithBytesNoCopy:).  Substrings created from such a string
apparently point into the same temporary buffer, even after the original
string is released, meaning that their contents become garbage as soon as the
buffer contents become invalid.

In the test case below, the contents of the NSString 'substr' change if the
temporary buffer is modified, even after the original string created from that
buffer is released. This is of course likely to lead to very nasty side

[bug #35699] NSStrings can point into garbage memory (misuse of app-supplied backing buffer)

Follow-up Comment #1, bug #35699 (project gnustep):

I looked at GSString.m a bit.
It seems that substring_c and substring_u should check the parent string's
_flags.owned and create a GSSubString only if the flag is true; otherwise they
should be conservative and create a regular string with a copy of the
characters/bytes.
