Use-after-free bug in img_cbk() about fast-livo HOT 3 CLOSED

Great discovery and a very practical tool! Additionally, could you share your configuration operation of AddressSanitizer in the project?

from fast-livo.

Tool usage reference:
https://github.com/google/sanitizers/wiki/AddressSanitizer

Usage:

1. Change the cmakelists.txt as below:

4,8c4
< SET(CMAKE_BUILD_TYPE "Debug")
<
< ADD_COMPILE_OPTIONS(-std=c++14 )
< ADD_COMPILE_OPTIONS(-std=c++14 )
< set( CMAKE_CXX_FLAGS "-std=c++14 -O3" )
---
> SET(CMAKE_BUILD_TYPE "")
16c12
< set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++14 -pthread -std=c++0x -std=c++14 -fexceptions")
---
> set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -pthread -fsanitize=address -O1 -fno-omit-frame-pointer -g -fexceptions")

2. Build fast-livo with cmake .. -DCMAKE_C_COMPILER=/path/to/clang -DCMAKE_CXX_COMPILER=/path/to/clang++ && make (clang must be used instead of gcc)
3. Run fast-livo to detect memory issues.

Following the steps above, maybe more issues could be found :)
