Which compiler version? I ask because this is not the first time we noticed some strange effect - where compiler versions did make some difference. Read: http://gnuada.sourceforge.net/pmwiki.php/Main/Performance It's a Wiki, you are welcome to add your experiences. A quote of the Fortran and C code - along with the compiler options - might be helpfull as well. Note that we also issued bug in bugzilla.
