Hi guys, I’ve built pytorch with asan, and I find that simply import torch then exit will trigger the asan’s fault. Is it expected? Here is my build script:
export DEBUG=1
export USE_CUDA=1
export DEBUG_CUDA=1
export CXXFLAGS="-fsanitize=address"
export CC="gcc"
export CXX="g++"
export USE_OPENMP=0
export USE_MKLDNN=0
export CUDA_HOME="~/micromamba/envs/cuda_env" # this is from conda environment
python ./setup.py develop
My start script:
export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libasan.so.6
export ASAN_OPTIONS="detect_odr_violation=0"
python ./1.py # 1.py just contain `import torch`
