Definitely not 1. 4 is always the case - every run is with different data.
2 and 3 I don’t know. What is boost and how does Python use it? None of my
code is importing it. How can get a stack trace when it crashes with just
that message?

1 a change to Python interpreter being used

2 a change to the boost library being used

3 a change to lower levels in 'the s/w stack' or h/w

4 a change to the data being passed-across

terminate called after throwing an instance of 'boost::python::error_already_set

[Larry Martell]

I have a script that has literally been running for 10 years.
Suddenly, for some runs it crashes with the error:

terminate called after throwing an instance of 'boost::python::error_already_set

No stack trace. Anyone have any thoughts on what could cause this
and/or how I can track it down?

You probably also have Python 3.8 on the path, and it's finding that one 
first.


These days it's recommended to use the Python Launcher, "py". That lets 
you specify which version of Python you want to use.
