Jack DeVries  added the comment:

What about low recursion limits? This program causes a segfault for me::

import sys
sys.setrecursionlimit(4)

print('goodbye, world')

[issue44393] segfault with sys.setrecursionlimit

[Eric V. Smith]

Eric V. Smith  added the comment:

That's the documented behavior: "A user may need to set the limit higher when 
they have a program that requires deep recursion and a platform that supports a 
higher limit. This should be done with care, because a too-high limit can lead 
to a crash."

[issue44393] segfault with sys.setrecursionlimit

[Alex Hall]

New submission from Alex Hall :

Found on:
Python 3.9.5
GCC 11.1 on Linux (x86_64)
Reproduced on:
Python 3.9.5
Clang 9.0.8 Linux (arm)

When setting the recursion limit to a high enough amount, trying to reach that 
recursion limit ends in a segmentation fault (stack overflow?)

code:
```py
import sys

def recurse(n: int) -> int:
recurse(n)

sys.setrecursionlimit(2**16-1)

recurse(100)
```
