Segmentation Fault in snd_pcm_rate_hw_free()

[Valentin Corfu <corfuvalentin@gmail.com>]

Hello ALSA developers,

I observed one segmentation fault in snd_pcm_rate_hw_free() function, 
with the following BT:

Could you please give me some hints how to solve this issue?

I can provide you more info or the test application, if needed.
I can see the issue every time, and I also checked with latest version 
of alsa-lib but I got the same results.

Thank you,
Valentin Corfu
