alsa-project/alsa-lib issue #341 was opened from imyxh:

The following code segfaults on the call to `snd_pcm_hw_params_free` on my machine:

```c #include <alsa/asoundlib.h> void main() { snd_pcm_hw_params_t *params; snd_pcm_hw_params_alloca(&params); snd_pcm_hw_params_free(params); } ```

The same goes for `s/hw/sw/g`. Am I doing something wrong? In more complex examples it seems to fail with munmap_chunk complaining about an invalid pointer, or free complaining about an invalid size.

How are the `*_params_free` functions meant to be used?
