# Now choose an example of something you'd like to test with ASAN.  This could be a specific python test we want to run in a loop, it could be a C++ unit test written to expose leaks, etc.
# In our case we use a small Gluon python tests as an example.
# First we'll will enter our container, and then we'll run tests within the container.
docker run --privileged -v `pwd`:/work/mxnet -v `pwd`/build:/work/build  -ti mxnetci/build.ubuntu_cpu bash

# Now within the container:
export PYTHONPATH=./python/
export MXNET_MKLDNN_DEBUG=1  # Ignored if not present
export MXNET_STORAGE_FALLBACK_LOG_VERBOSE=0
# Feel free to export any ASAN options via export ASAN_OPTIONS=...

# Importantly we need to make sure ASAN is the first library loaded (before our other libraries have a chance to allocate memory)
# To do this we add the library to the library preload list
