Did anyone upstream look into a compatibility environment variable that
could be exported to change the direction of the memcpy? Yes, it's a
hack, but it would allow affected users to have an option.
Alternatively, I agree that this is one case where a wrapper hack would
also work for the flash plugin. I suspect, however, that other projects
will be affected and so a generic solution would help.
