After downloading and decompressing the latest 3.6.2 source release, I attempted to build as follows:

    $ ./configure --enable-optimizations --enable-ipv6  # seems fine
    $ make -s -j$(nproc)

At the end of the build I have this error reported:

    Failed to build these modules:
    Following modules built successfully but were removed because they could not be imported:
    _asyncio              _ssl

Scrolling up, I see that the _asyncio and _ssl failures are due to _socket being missing. Scrolling up further, I see several warnings and errors, to wit:

    *a series of tests that seem to go okay*

After this, the build seems to think all the tests are done and continues with "Rebuilding with profile guided optimizations:". There are a lot of warnings here, mostly about missing execution counts, which I assume comes from 3/4 of the tests not being run. Later on, however, we have this gem:

    Please submit a full bug report,
    with preprocessed source if appropriate.
    See <file:///usr/share/doc/gcc-4.8/README.Bugs> for instructions.
    Preprocessed source stored into /tmp/ccMFxPIP.out file, please attach this to your bugreport.
    ERROR: Cannot create report: [Errno 17] File exists: '/var/crash/_usr_lib_gcc_x86_64-linux-gnu_4.8_cc1.1000.crash'

I have gcc (Ubuntu 4.8.4-2ubuntu~14.04.3) 4.8.4

I'm new to building Python and even newer to reporting bugs here, so please let me know what additional information I should provide or steps I should take.
