when back the app .it is :call to OpenGL ES API with no current context (logged once per thread)

What steps will reproduce the problem?
1. run one time it is ok. touch back button it is error:call to OpenGL ES API 
with no current context (logged once per thread)
2. run second time is crash error:Fatal signal 7 (SIGBUS) at 0x00000000 
(code=128)
Fatal signal 11 (SIGSEGV) at 0x0000000c (code=1)

What is the expected output? What do you see instead?
