Message "test test_gdb failed" while installing Python-3.5.1 on Linux

While installing Python-3.5.1 on Linux ubuntu 14.04 LTS, after running command:

make test

I got a message:

test test_gdb failed

I've made a single test with command:

./python -m test -v test_gdp

and I got this:

I have gdp installed.

How to fix it? Or can I just ignore it?
