printf and friend (ie, stdio) calls CHROUT.... i see no reason to use that by 
doing inline assembly hackery to be honest. (i have personally only ever used 
it either for simple testing, placing an inc$d020 somewhere or sth, or really 
really c64 specific hackery) most standard tasks can be solved with the 
library calls.

yes...well to be exact, the behaviour is "undefined" (but most DO crash indeed
