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.

Hmmm, SLAB makes it trigger the null pointer less, not make it go away completely :(
