Stepping out while debugging causes the standalone player to freeze



To reproduce:
1. Build Angry bots x64 standalone on OSX 10.9
2. Put a breakpoint in FreeMovementMotor line 18
3. Pin some variables
4. Attach to player
5. Hit breakpoint, step through some code
5. Player crashes (stack trace attached)

Expected result: Debugging proceeds
Actual result: player freezes

*Note :

The issue is related to Stepping Out when debugging and is fixed. We found another issue related to Stepping Over which has the same result, the player freezing but it only occurs when using Step Over.

    On 4.3.1 on OS X Mavericks I can connect the debugger and even stop playing once. After that if I hit play again or try to compile scripts Unity locks up.

    The Debugging in Unity 4.3.1 with Mavericks is impossible for me at the moment. Unity and MD hanging ! Requiring the force-quitting Unity and MD.

    This says fixed, but it is absolutely not fixed for me or anyone on my team. Should I vote on this or will it just be ignored because of it's "fixed" status?

    Updated to 4.3.1 hoping the mono debugger freezing unity will be solved.. No such luck on Mavericks, MBR 2012

    Still happens for me in 4.3.1 + Mavericks on a MBP Early 2011. Makes it impossible to put breakpoints in Start() or Awake() methods

    After rebooting the whole machine, it's working again. Sorry but I don't think you have solved the race condition, you probably have just hidden it a little more.

    It's happening again in 4.3.1 after the patch. I've been working with it for a day, at first it stopped happening but it's happening again now in the usual workflow:
    - Attach process to unity debugger from Mono
    - Hit "Play" in Unity editor

    I can't understand how it's broken again. Should I reinstall or something??
