Partially. But I misread your log, too. Seems that gdb failed to
figure out how snd_pcm_t is actually defined. You'd try casting it to
struct _snd_pcm * if the type information got lost somewhere. (You'd
check the later by examining the `readelf -wi' output for your binary
or library you're hacking on.)
