[New-bugs-announce] [issue25262] Issues with BINUNICODE8 and BINBYTES8 opcodes in pickle

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

There are issues with BINUNICODE8 and BINBYTES8 opcodes in pickle.

1. Unpickling BINBYTES8 is not implemented in Python implementation.

2. Highest 32 bits of 64-bit size are silently ignored in C implementation on 32-bit platforms.

3. There are no tests for BINUNICODE8 and BINBYTES8.

Proposed patch fixes these issues.
