[issue23816] struct.unpack returns null pascal strings - [first] bug report

Xiang Zhang added the comment: Hmm, code->size is determined by repeat count at initilization stage so I don't understand why it should be updated in s_unpack_internal to 255. And the repro script works well for me. -- nosy: +xiang.zhang resolution: -> not a bug stage: -> resolved

[issue23816] struct.unpack returns null pascal strings - [first] bug report
