--- Comment #2 from Jan Pohanka <xhpohanka at gmail dot com> ---
I can also reproduce this bug using Axel's steps. 

This is the content of my ~/.gdbinit

add-auto-load-safe-path /home/honza/dev

python
import sys
sys.path.insert(0, '/home/honza/dev/gdb-pretty')
from libstdcxx.v6.printers import register_libstdcxx_printers
register_libstdcxx_printers (None)
end

set print pretty on
set print object on
set print static-members on
set print vtbl on
set print demangle on
set demangle-style gnu-v3

On https://sourceware.org/gdb/wiki/STLSupport there is a description how to get
the pretty printers.

After passing the MI commands to GDB as Axel described, I'm getting following
error

~"/home/zumbi/gdb-7.6.1/gdb/varobj.c:3532: internal-error: c_value_of_variable:
