Do you have a few more messages in the kernel logs that given more
details about the segmentation fault?

Otherwise, do "ulimit -c unlimited", run the crashing application, it
will generate a 'core' file. Transfer it to your development PC, and
run cross-gdb on it:

	./output/host/usr/bin/arm-linux-gdb -c core ./output/target/usr/bin/aplay

and then see what's the reason of the segmentation fault.

Also, could you post on http://code.bulix.org your Buildroot .config
and give us the link? Just to check there isn't anything obviously
wrong in your configuration file.

Best regards,

Thomas
