Possible cause of error:
Trying to modify MonoBehavior and it's children Objects before Start() method.
I had to rewrite some code to fix this issue to make sure no manipulations on MonoBehaviour are done before Start().
Important note: Errors persist till system restart. YOU NEED TO RESTART WINDOWS.
I had this error in ALL unity versions, I tried to remove library folder, VS solution files, erase completly and resync from collab, deleting unity configuration files - nothing helped me till I modified my code.

Unity 2017.3.0f3
Assertion failed: TLS Allocator ALLOC_TEMP_THREAD, underlying allocator ALLOC_TEMP_THREAD has unfreed allocations, size 69
Would really appriciate a fix as I can no longer build for IOS.

I've deleted the folder Library, obj and UnityPackageManager, started Unity again, all the things were imported again (hours of work lost) and then the error was gone. But just for a few hours. Now it's happening again. As I can see on Google, this error is old, really old. The guys from Unity say they fixed it over and over again in every thread (there's a lot), but the truth is it was never fixed and maybe they just don't know what causes it and how to fix it.

No, I think it doesn't affect the build. But it is extremely annoying coz it's impossible to debug in play mode

In my case, I updated Unity from 5.6 to 2017.3.0p3
It was fine when platform was pc,mac but as soon as I converted to android, got this error.
Assertion failed: TLS Allocator 'ALLOC_TEMP_THREAD, underlying allocator ALLOC_TEMP_THREAD has unfreed allocations, size 11184864'
Also, in play mode, I got this error !
Is there any temporary solution??
And... is it critical for Android, iOS App (release version) ??
