Follow-up Comment #9, bug #50811 (project avr-libc): Re. the "compiler thing" mentioned above: avr-gcc might replace a call to printf by a call to puts provided the arguments of printf allows to do so. You can avoid this optimization by means of -fno-builtin-printf which takes away any knowledge (except prototype information) about printf from the compiler. This will result in a call to printf (which you are using anyway), saving the call to fputs. _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/bugs/?50811> _______________________________________________ Message sent via/by Savannah http://savannah.nongnu.org/
