4.6.8p3 unity crash when program exits normally

sometimes when I exit game normally in ios, crash can be issued. the following is callstack:

libsystem_kernel.dylib 0x00000001989171e0 __pthread_kill + 8
libsystem_c.dylib 0x000000019888ab78 abort + 132

0x0000000100a7e63c UnityCleanup (LibEntryPoint.mm:239)

I use unity4.6.8p3, I found unity added a function in 4.6.8 in releasenote as follows:

• (665246) - Animation: Remove relative material property blocks when the animator component is being removed.

I think that it may make a bug which leads to this crash.

Could you help me? thanks!

 

I am having the same problem on ios7.1, built by unity4.6.9f1

 

yes, I have the same issues on almost all ios devices, unity4.6.9f1

On 4.6.9f1, Xcode 7, IL2PCC, happening on wide range of iOS devices, iPhone / iPad, 32 / 64 bit

I met the same problem, and this crash log is full of my crash collection service.
I want to fix and remove this. How can I fix it?

 

@little_bunny @bisey, have your resolve this problem?
