Inconsistent TokenStreamRewriter.InsertBefore() behavior with C "do-while();" statements - parsing

I am trying to instrument C code with ANTLR listener mechanism. But I found some inconsistent behavior of the TokenStreamRewriter.InsertBefore() API with the C do-while(); statement.
I have posted a detailed description as ANTLR Issue #2252. So I won't duplicate it here.
Anyone met the same issue?

Issue solved. Turns out my assumption of the behavior of InsertBefore/After() is incorrect. I posted the detailed explanation to the Issue #2252. Hope it can help someone as confused.

For those who have changed from parse to backendless....Do you have issued with ARC in Xcode?

We have changed from Parse to Backendless and it seems that deallocation of DateFromatter is not being done efficiently. Does anyone have thoughts on this? or has experienced similar problems.
Best,

Implementing Google Play Games Services in Swift

Hello fellow developers :)
I have been trying to implement Google Play Games Services in my newest app project, but find myself being completely lost. I find GMS to be quite complicated and therefore need some sort of tutorial to stand a chance.
Unfortunately the official guide on Googles websites (https://developers.google.com/games/services/ios/quickstart) only describes the setup process for Objective-C.
My question is therefore, as ambiguous as is, if anyone knows anything that could help me implement GMS. This includes links to tutorials, code-snippets, personal tips, or anything else that could come in handy.
And yes, I am aware that questions like these are often frowned upon due to their ambiguous nature. What must be understood is that this question is a desperate last attempt before giving up and going with GameCenter instead. I simply have not found the information needed anywhere else.
Thank you! :)
You may need to use a bridging header for this. Check out the following link by gguuss in GitHub: http://github.com/gguuss/gplus-ios-swift.

Find the source for __lldb_unnamed_function4866$$ProjectName

I got an EXC_BAD_ACCESS in my iOS program, and I suspect that the cause is in one of my anonymous blocks, but there are quite a few of those, and I need to narrow down the candidate list a bit.
The stack trace shows the current frame as __lldb_unnamed_function4866$$ProjectName. There are no line numbers or source file names that I can see. No local variables visible either. The debugger shows machine code instructions. This was running on a background event queue, so there is none of my code anywhere else on the stack.
How do I go about finding out what function this is?
I came across a similar situation, and while I can't help (yet) with your problem, I think I know a man who can.
Check out http://www.realmacsoftware.com/blog/block-debugging, for an exposition of how to find out a lot more about the evil block in question.
It doesn't help me much, because I'm working from a crash log, but if you're still interested, this is going to give you just about as much as you can get about the unnamed block.
Warning, the above link exposes you to a lot of arcane knowledge, and may make you feel a little inadequate :)
[Editted to add]
Not good enough yet?
After searching through disassembly and doing some manual symbolication, I came to the conclusion that the ___lldb_unnamed_function is a red herring.
I followed How to manually symbolicate a crash log with atos, and it pointed the finger at a completely different function, which came from a 3rd party library, and was a very good candidate for the crash reason (killed by angry watchdog with badf00d.)
In the course of this enquiry, I also came across hopper, a great disassembler; I used the demo version to confirm what the suspicious code was doing, so I'm giving them a namecheck.
Try to set an exception breakpoint by clicking on the plus symbol within the breakpoint navigator cmd + 6.

What is the main purpose of WebExceptionStatus.Success?

I am a bit confused about the purpose of the enum value Success of the WebExceptionStatus enumeration. I did a search and did not find this enumeration being used outside the WebException class. This is very confusing to me. Why would an exception be used to indicate a successful action/state. Am I missing something, or did I not search thouroughly enough? Was it introduced for future functionality?
Please if anyone does know its basic purpose I would be thankfull if s/he shares with us the explanation.
See if this might help.

What might cause IDirectDrawSurface::Release blocks and never return?

DirectDraw 7 is very old APIs but we have a lot legacy code written on that.
Recently I found that directdraw might block on some of it's interface calls, like IDirectDrawSurface::Release, and never never return. But some times they don't.
I can not find any information by Google so I came here.
Hope you can help me or tell me where I can find help.
Thanks a lot.
A deadlock would imply that you are multi-threading DirectDraw? This isn't a safe plan. You should avoid doing it.
Apologies if this isn't the cause.
