[New-bugs-announce] [issue43610] Ctrl C makes interpreter exit

[Xinmeng Xia]

New submission from Xinmeng Xia <xiaxm at smail.nju.edu.cn>:

Python interpreter will exit when using Ctrl C to interrupt some Python module functions with read operations. e.g.  sndhdr.what(0), pdb.find_function('abs/'*100000,False), mimetypes.read_mime_types(0).  This is not the expected behavior.  Ctrl C is to raise a KeyboardInterrupt, it should not crash Python and make interpreter exit.

Reproduce:
1. type 'python3' in command console;
2. type 'import sndhdr;sndhdr.what(0)'
3. type ctrl C

Expected behavior:  type ctrl c, raise a KeyboardInterrupt,  Python does not exit.
