[BUG] -- asan triggers traceback of capstone in ubuntu-arm64

[Sunxingzhezhexingsun]

Describe the bug
When I tested asan with "user_space" in the demos directory on an AArch64 ubuntu system, I encountered the following traceback:

$ gcc -O0 -ggdb -Wall -Wpedantic -Wextra -fPIC -fPIE -pie ./stack.c -o stack
...
$ ./retrowrite --asan ./stack ./stack.asan.s
