[issue46110] compile("-"*3000000 + "4", '', mode) causes hard crash

[Guido van Rossum]

Guido van Rossum <guido at python.org> added the comment:

So if I understand the speed.python.org results correctly, the time to run `python -c pass` went way up, but the time for `python -S -c pass` did not go up significantly.

Unfortunately the only machine I have access to is a Mac, and I cannot repro this result, using PGO/LTO. Could it be a Linux thing? Or due to something in the venv for pyperformance?

Note that I am using a much simpler test script: Tools/scripts/startuptime.py. I have not yet succeeded in building and running pyperformance, mostly since the Python I build doesn't have SSL configured (I always forget the flag to use on my machine) and pyperformance insists on installing a bunch of stuff (including new versions of pip and setuptools, it seels).

Can anyone repro the perf regression on their box?
