Is this expected are did I something wrong?

Those lines have been subject to a few changes, partly triggered by
changes in standard and/or compiler.

Possibly the following is needed?

commit 67cd07e55d5ec908c246ae543e480d367b61d6b3
Author: David Kastrup address@hidden
Date: Fri Jun 3 14:21:55 2016 +0200

Issue 4878: Make type_p_name_ always char pointer

This avoids the pitfalls cured by issue 4783 without the
associated inconvenience when no predicate is desired.

And possibly this before it?

commit c6758d6d12e33779fc81218693d5650682d8a1ca
Author: David Kastrup address@hidden
Date: Thu Mar 3 00:32:33 2016 +0100

Remove Smob::type_p_name_ default

This was the single most problematic thing across C++ compilers and standards.
Foregoing it means a hassle, but using it turned out to be worse.
