New submission from Jon Åslund <[email protected]>:
Some bytes that are non utf-8 segfaults python repl in 3.10 and later on linux.
Example:
$ python3.10
Python 3.10.4 (main, Mar 24 2022, 14:20:44) [GCC 9.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> �
Segmentation fault (core dumped)
It is treated correctly in Python 3.9 and earlier
$ python3.9
Python 3.9.12 (main, Mar 24 2022, 14:21:53)
[GCC 9.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> �
File "<stdin>", line 0
SyntaxError: (unicode error) 'utf-8' codec can't decode byte 0xb6 in position
0: invalid start byte
How to reproduce:
In Gnome on Ubuntu 20.04 with the Swedish keyboard layout, holding left alt and
pressing the ö key enters the byte 0xb6 into the terminal.
I have only been able to make it crash the repl. I can't make it crash the
parser. For instance trying to eval the byte.
