That doesn't entirely solve the problem, see quote and reply in

I think adding errmsg_raw() or somesuch that doesn't allocate any memory
and only accepts constant strings could solve the problem more
completely, at the obvious price of not allowing translated strings
directly.
Those could be pretranslated during startup, but thats mighty ugly.
