# To use in py_test, add the following to the test target:
#    env = {
#        "LD_PRELOAD": "/usr/lib/gcc/x86_64-linux-gnu/11/libasan.so /usr/lib/x86_64-linux-gnu/libstdc++.so.6",
#    },
# To use static link flags, see the following:
# build:asan --copt -static-libasan
# build:asan --linkopt -static-libasan

# Other debugging techniques:
# Run the binary directly from bazel-bin with gdb:
#   bazel build //path/to:test # see stdout for the path to the binary
#   gdb --args python bazel-bin/path/to/binary
#
# Run the test under valgrind:
#   bazel test -c dbg //path/to:test --run_under=valgrind
