If so, there is a gcc optimisation bug that causes a refinement error (like above). http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27363 Fwiw, Openembedded builds a working toolchain for ARM and ALSA. > Should I provide more debugging output like RULES_DEBUG output from > sound/core/pcm_native.c? > Yes please.
