Microsoft VC shows the same behaviour. lf is a perfectly appropriate format specifier for double. If you say to output the next field using a %Lf, then printf() will assume that a long double is waiting there. an integer is the next variable on the stack, then printf() will output garbage. printf() is not type safe.
