Crash inside alsa library when running example

I tried running the blocking api example [1] in a test project and it crashed. It crashes inside an alsa lib function after calling stream.get_stream_write_available in the example code. This is under Gentoo linux x86_64 with Rust 1.0 stable and rust-portaudio 0.4.17

Closing as it is old issue and dump is no longer present.
