Hi

     This patch fix failures when _GLIBCXX_INLINE_VERSION mode and running:

make check-debug RUNTESTFLAGS=prettyprinters.exp

     libstdc++: [_GLIBCXX_INLINE_VERSION] Add gdb pretty print for 
_GLIBCXX_DEBUG

     In _GLIBCXX_DEBUG mode containers are in std::__debug namespace but 
not template
     parameters. In _GLIBCXX_INLINE_VERSION mode most types are in 
std::__8 namespace but
     not std::__debug containers. We need to register specific type 
printers for this
     combination.

     libstdc++-v3/ChangeLog:

             * python/libstdcxx/v6/printers.py 
(add_one_template_type_printer): Register
             printer for types in std::__debug namespace with template 
parameters in std::__8
             namespace.

Ok to commit ?
