------- Comment #1 from burnus at gcc dot gnu dot org 2008-01-17 22:45 ------- Thanks for the bug report; however, I fail to reproduce the bug with either of 4.1.3, 4.2.2 and 4.3.0 on x86-64-linux.
Your version "4.2.0 (experimental)" is relatively old. (Even 4.1.3 might contain a bug fix, which was not in yet in 4.2.0.) Can you try with a newer version, for instance the one available from http://gcc.gnu.org/wiki/GFortranBinaries ? * * * The newest gfortran versions also have the following warning by default: weights = rate_err**-2.0 1 Warning: Extension: Unary operator following arithmetic operator (use parentheses) at (1) This is not only invalid Fortran but also not always well defined. What does the following mean: "a**-b*c" Does mean "a**(-b) * c" or "a**(-b*c)" - different compilers make different choices here. (In your case the choice is unambiguous but still not standard conform.) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34837
