Some tarfiles in the wild have garbage in the last 12 padding bytes before a 512 byte block boundary rather than 0s – likely because they aren’t initializing the unused space. The check at line 377 of Archive/Tar.pm should be allowed to be skipped for users who don’t require strict conformance and instead need to open every possible tar file. Any config method is fine such as IGNORE_PADDING_CHECK
