The above seems like you're trying to use AS just for the package, but that cannot work, because it's missing all the AS runtime libraries which must be in the main executable -- i.e. R.

Actually, it may work (does in gcc 4.8.2 for example), if you *link* the 
package with -faddress=sanitize.

See the current 'Writing R Examples' manual.
