backtrace from npm core dump

I have attached a back trace from the npm crash.  I see
node::os::GetInterfaceAddresses is called so as an experiment i tried the
following javascript

    var os = require('os');
    var ifaces = os.networkInterfaces();
    console.log(ifaces);

This produces the same back trace as running npm.  Running this code using
glibc works.  So it seems the issues is npm is using os.networkInterfaces()
which works with glibc but not uclibc.

You can find the code for node::os::GetInterfaceAddresses in node.js v0.12.7
here
https://github.com/nodejs/node/blob/d3492aa7b386946e3a156440cad346e5b0a82838/src/node_os.cc#L225-L300.

The back trace shows the crash is in OneByteString which is called in several
places in node::os::GetInterfaceAddresses.  The data it's operating on comes
from a call to uv_interface_addresses() which is part libuv that's in node.js. 
The code for uv_interface_addresses() is here
https://github.com/nodejs/node/blob/d3492aa7b386946e3a156440cad346e5b0a82838/deps/uv/src/unix/linux-core.c#L786-L878.

I suspect uv_interface_addresses() is where the issue lies.
