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.

    @Unity Devs - This issue is not specific to the repro steps above, it happens with every single one of my projects. Attach MonoDevelop to Unity Run and Debug hit a breakpoint. Stop running and try to run again and Unity becomes unresponsive. Then you must force quit unity, quit monodevelop, then open unity, then open monodevelop. Rinse and repeat, the same every time.

    Yes please vote for this issue. This makes using Unity extremely frustrating, I can't believe that this is ranked as a Priority 3 issue. It has been happening for several versions, and did not get any better with version Unity 4.3.3f1. Someone please fix this!!!!

    MonoDevelop is open source, so possibly a workaround/fix exists there. Who will donate me some money if I can solve the issue? (half-joking)

    Unity 4.3.x
    OSX 10.7.5 (Lion)

    Same issue, cannot but breakpoint (never had any issues with Unity 4.2).

    As IQPierce mentionned, this is a super critical bug. I do not get how the IDE integration can be SO broken (cannot debug, can't even open the correct project most of the time when working on multiple projects at once, etc) on OSX and Windows and this not being a top priority bug. This is turning professional developers away from Unity...

    OSX 10.8.5
    Unity 4.3.3f1
    Unity is freezing after running the debugger about 75% of the time. Usually works the first time I run it then if I leave the debugger attached and run the game again unity will freeze

    Same here; totally useless on the Mac (Maverick with Unity 4.3.3f1); sometimes it works, sometimes it doesn't. It's not a small problem, it's a showstopper for many people.

    Do we have any kind of workaround?

    Have this issue for a long time: when monodevelop connected to editor, editor will freeze when trying to launch play mode. Actual for several versions of Unity, since about 4.2 until current 4.3.3

    I'm experiencing this on OS X 10.9.1 and Unity 4.3.3f1. I really hope this is fixed soon. It's discouraging to see that this has been happening since November 20th, two months ago.

    More than 1 month has passed and no solution in 4.3.3 to this yet :(
