I've traced the bug down to this code: http://gcc.gnu.org/viewcvs/trunk/libgfortran/io/write_float.def?r1=173231&r2=173408&pathrev=173408 + rchar = '0'; + if (w > 0 && d == 0 && p == 0) + nbefore = 1; + /* Scan for trailing zeros to see if we really need to round it. */ which I don't understand. Why are we setting the number of digits before the decimal point to 1 if the width is zero and the scale factor is zero and the number of requested digits after the decimal point is zero?
