module.c:101 assert

Created by: varun729

Describe the bug Running DynamoRIO with python application that uses Tensorflow results in a crash. DynamoRIO can successfully run with a trivial helloworld python program, and even with a python application that uses PyTorch.

The goal is to use dynamorio with drcachesim to collect memory trace, but it crashes. This is similar to the issue #2929 and the suggestion there was to try debugging without any DynamoRIO client. So, providing details here from the debug run.

To Reproduce Steps to reproduce the behavior:

Run the python 3.7 with tensorflow 1.15 installed in Anaconda environment.
Precise command line for running the application.

drrun -debug -- python -c "import tensorflow as tf"

Exact output or incorrect behavior. debug_drio_python_tensorflow.txt

Please also answer these questions:

What happens when you run without any client? Crashes
What happens when you run with debug build ("-debug" flag to drrun/drconfig/drinject)? Throws assert at core/unix/module.c:101

Expected behavior Program should run to completion when run without any client.
