Description
The Python code in a Docker container running Ubuntu bionic with Python 3.7.3 throws munmap_chunk(): invalid pointer(), I used memory profiling to monitor the amount of memory used and its at max 160MB, the Docker container has 1024MB assigned to it.
Through GDB I received the following backtrace which points to numpy free cache snippets in the source code.
