RE: printers.py issue

["Hoyer, David" <David.Hoyer@netapp.com>]

I just realized that some of my original email explaining the issue was removed from the thread

Problem 1:  the function find_type was changed such that search now uses typ.unqualified() instead of typ.name.
In the case of a class, the former prepends class to the search string so that when it runs gdb.lookup_type(search), it does not find the definition.   If I switch it back to typ.name, this function works

Problem 2:  We are seeing an error in strip_versioned_namespace
  File "/usr/lib/x86_64-linux-gnu/../../share/gcc-8/python/libstdcxx/v6/printers.py", line 668, in __init__
      self.typename = strip_versioned_namespace(typename)
  File "/usr/lib/x86_64-linux-gnu/../../share/gcc-8/python/libstdcxx/v6/printers.py", line 114, in strip_versioned_namespace
    return typename.replace(_versioned_namespace, '')
AttributeError: 'gdb.Type' object has no attribute 'replace'
Error occurred in Python command: 'gdb.Type' object has no attribute 'replace'

We are noticing some problems using GDB with printers.py

This belongs on the libstdc++ list, CC'd.

Which version of GDB are you using, and which version of Python does it use?
