Anyway, this is fine, the code seems to be prepared for > that case: elements is set to 3 in server.cc:128. apt is since 0.8.0~pre2 (23 Aug 2010). I think back then it was also a sourceforge server triggering this. Note that this is a violation of the HTTP1.1 spec (see rfc7230 section 3.1.2) which allows for an empty reason-phrase, but the space before that is non-optional. > However, Owner is NULL (I don't know why, I don't know the code, but > it is) so Owner->Debug fails in server.cc:132. > > The attached patch checks whether Owner is NULL before dereferencing > it.

'Owner' refers here to the ServerMethod owning the ServerState (that was a very helpful explanation, wasn't it? ;) ). It boils down to this: In Sep 2013 I wanted to fix some bugs in https by using less curl and more of our own http code. For this I invented a bunch of Server classes as parents for http and https – in handsight, I really should have used another name, but well, anyway – expect that both were completely different in their implementation. Somehow I managed to pull it of anyway with the result that they share most of their State parsing/tracking which is quite helpful. It also means through that the actual Methods using the State are still very different so getting a common interface for them was hard. Somewhere down that line I took a shortcut giving the HttpsState a NULL for its owner as it 'never' really needed it and can hence be fixed 'later' correctly, right? Fast forward one and a half years and the 'never' as well as the 'later' is spoiled. Its a bit ironic that a debug message does this to me… </rambling> The proposed patch works just fine as the other users for 'Owner' aren't used by https and for http its always properly set (and nobody dies if a debug message isn't shown even if requested) and at that point in the release I guess everyone will be happy about a one-line fix. (Michael is uploading it any minute now) Attached is my fullblown 'proper' patch with a testcase I am going to apply to our /experimental branch for comparison in the meantime.
