Hi,
by Clem Dickey and Jonathan Wakely:
https://bugzilla.redhat.com/show_bug.cgi?id=1085576
https://sourceware.org/bugzilla/show_bug.cgi?id=17136
if you debug any program then register the type printer with the current
objfile, running 'info type-printers' results in a python exception:
(gdb) info type-printers
Python Exception <type 'exceptions.AttributeError'> 'gdb.Objfile' object has no attribute 'name':
Error occurred in Python command: 'gdb.Objfile' object has no attribute 'name'
->
(gdb) info type-printers
Type printers for /lib64/libstdc++.so.6:
basic_string_view<C>
deque<T>
...
unordered_set<T>
vector<T>
The exception doesn't happen if the type printer is registered globally, by
passing None instead of gdb.current_objfile().

The patch can be checked in IMO.
Given that I don't have the time to write a testcase myself
I'm not going to force someone else to.
Another reviewer may require one though.
