GFF_MJ(3248,0x103f9ab80) malloc: *** set a breakpoint in malloc_error_break to debug
Error screenshot:
After running for a while, the app always crashes, but I won't get any information except the above tips. Now I don't know how to solve it, who can help me?
Thank you.

Heap corruption occurs when a program damages the allocator's view of the heap. The outcome can be relatively benign and cause a memory leak (where some memory isn't returned to the heap and is inaccessible to the program afterward), or it may be fatal and cause a memory fault, usually within the allocator itself.
These bugs are no fun. Most likely, you have a buffer overflow somewhere or you are using a piece of memory after it has been freed and stomping on something else.
Since you can get it to crash in the debugger, that makes it much easier to track down.
Start by setting a breakpoint on malloc_error_break, as the error message instructs you to do. When you hit that breakpoint, that'll provide more of a clue, but still may be rather vague. However, you'll be able to post more clues and we can help you from there.
