If you are running in Firefox with asm.js enabled (by using the fastcomp backend, or in the old backend specifying -O1 or greater), the "too many local variables" limit should not apply. If you still get that error in Firefox with asm.js-enabled code, it's possible that the output did not validate properly as asm.js. Try looking for "asm.js compilation succeeded" message in the log, or if there was an error message of some sorts, that caused the output to not validate, which then would subsequently hit the too many local variables limitation.
