[New-bugs-announce] [issue23228] Crashes when tarfile contains a symlink and unpack directory contain it too

[Michael Vogt]

New submission from Michael Vogt:

The tarfile.makelink() code crashes with a maximum recursion error when it unpacks a tarfile that contains a symlink into a directory that already contains this symlink.

Attached is a standalone testcase (that probably better explains whats going on :) and a possible fix.
