[alsa-devel] Infinite loop in snd_pcm_hw_htimestamp() for capture PCMs?

I've found some unexpected behavior in alsa-lib. The attached program
uses 100% CPU in an infinite loop, when I'd expect it to return either
an error or a valid htimestamp. I believe the loop occurs in
<src/pcm/pcm_hw.c:snd_pcm_hw_htimestamp()>. Am I not supposed to call
htimestamp() on this type of PCM? Is the PCM still in an invalid state
when htimestamp() is called?
Card: HDA ATI SB
Chip: Realtek ALC889
Happy for any insight.
