[SDL] SDL Audio Memory Errors

[Bob Pendleton]

The first thing I noticed is that the error occurs in libasound, not
in code that is part of the SDL code base. Have you verified that the
error is the result of a parameter created in SDL? That is, is there
anything the maintainers of SDL could possibly do the correct the
error?
