In Unity3d 2017.3.0F3 has been an error: "Assertion Failed:tls Allocator alloc_temp_thread, underlying Allocator Alloc_temp_thread has Unfreed allocations, size 87488 "

Activating and deactivating a game object will be reported once into play mode is a crazy error

Search in issue Tracker the same error was encountered in iOS development but I am an Android environment .....

0x1 resolution

Put file > Build Settings > Player Settings > Other Settings > Configuration > Scripting Runtime Version from. Net3.5 changed to. Net4.6, and then reboot unity found no error.

Then one more time to change back. Net3.5, restart, or not continue to error √ Magic

For reference only, because not sure whether everyone out of the same problem ~
