Correct. I suspect that somewhere in alsa-lib code is not checking an
error return on a memory allocation. When I previously discussed this
issue with the folks on alsa-devel they suspected a bug in alsa-lib.
I'll give them this additional data and see if someone there wants to
help track down the root cause.
