在使用 ctypes 加载到 python 的 C/C++ 库上使用内存清理器 (asan)

Question

我有 C++ 库用 AddressSanitizer(asan) 使用

g++

和

cmake

编译：

SET( AXULIARY_COMPILE_FLAGS "-g -Og -fsanitize=address -fno-omit-frame-pointer")

这在运行独立的 C/C++ 可执行程序时效果很好。但是当使用

.so

:

 作为共享/动态库 (

ctypes

) 加载到 python 中时，我无法使其工作

run.sh:

#!/bin/bash
#LD_PRELOAD=/usr/lib/gcc/x86_64-linux-gnu/11/libasan.so
LD_PRELOAD=$(g++ -print-file-name=libasan.so)
echo   $LD_PRELOAD
export $LD_PRELOAD
python3 run_asan.py

run_asan.py:

import ctypes ;print("DEBUG 1 ")
asan = ctypes.CDLL(  "/usr/lib/gcc/x86_64-linux-gnu/11/libasan.so", mode=ctypes.RTLD_LOCAL )                ;print("DEBUG 2 ")
lib  = ctypes.CDLL(  "../../cpp/Build/libs/Molecular/libMMFFsp3_lib.so", mode=ctypes.RTLD_LOCAL )           ;print("DEBUG 3 ")

不断收到此错误：

prokop@DesktopGTX3060:~/git/FireCore/tests/tMMFFsp3$ ./run.sh
/usr/lib/gcc/x86_64-linux-gnu/11/libasan.so
./run.sh-: line 7: export: `/usr/lib/gcc/x86_64-linux-gnu/11/libasan.so': not a valid identifier
DEBUG 1 
==20016==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD.

我也试图将 asan 与 cmake 静态链接，但这也不起作用：

run_asan.py

import ctypes; print("DEBUG 1 ")
lib  = ctypes.CDLL(  "../../cpp/Build/libs/Molecular/libMMFFsp3_lib.so", mode=ctypes.RTLD_LOCAL )  

prokop@DesktopGTX3060:~/git/FireCore/tests/tMMFFsp3$ python3 run_asan.py
