Every time. These exact same parameters and flags worked with 3.6.2 with no issue, but they die on 3.6.3

I close the issue as out of date, since there is no activity for 4 years. Maybe it was fixed in the meanwhile.

If it's not the case, please reopen the issue. If someone can still reproduce the issue, it would help to write a short reproducer script based on the test causing the crash.
