[New-bugs-announce] [issue23321] Crash in str.decode() with special error handler

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

Debugging build crashes in some circumstances in str.decode() with error handler which produces replacement string with length larger than malformed data. For example the backslashreplace error handler produces 4-character string for every illegal byte. All other standard error handlers produce no longer than 1 character for every illegal unit.

Here is a patch which fixes this issue. I'll commit it without review because buildbots are broken without it. This issue is open for reference and post-commit review.
