------- Comment #2 from jvdelisle at gcc dot gnu dot org 2008-03-01 16:06 ------- Are you using your own build of gfortran on mingw or one obtained from elsewhere and where?
Are the time intervals so short that you could be seeing roundoff? Could the time intervals be wrapping around? The last modification to cpu_time was in 12-25-2007. Do you have an idea when this last worked for you? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35355
