Description

Hey great library!
I'm curious about why this function crashes on large assignment problems.
It worked for me for 5000 and 10,000 position problems but crashed for 55,000 immediately.
At first I thought it was a memory issue but it seems to be crashing long before exhausting all the memory on the machines I tried.
Do you have any idea why?

Research direction

No source file, test, or entry point is named. Start by reproducing the assignment problem at 5,000, 10,000, and 55,000 positions while monitoring the crash and memory usage; done means the cause of the large-input failure is identified and the 55,000-position case no longer crashes unexpectedly.
