Any workaround would be much appreciated. This looks like a problem with whatever C library you are using, not with gcc itself. gcc does not provide sprintf. It is possible that there could be a compiler problem here related to passing float to a varargs function, but I don't see how that could wind up producing ",," no matter how much it messed up. It is of course also possible that c_var3 is getting clobbered somewhere before you print it. Ian
