From: "Olofsen, E. (ANST)" E.Olofsen@lumc.nl Subject: [NMusers] g77 optimization fails with current versions Date: 12/11/2003 9:28 AM Dear NONMEM users, NONMEM + ADVAN3 compiled using g77 versions 3.2.2 and 3.2.3 with -O3 (and possibly with -O2 and other versions) may produce error messages such as PK PARAMETER FOR K12 IS NON-POSITIVE or PRED RETURNS DIFFERENT OUTPUTS WITH THE SAME INPUTS When I compiled PREDI with -O3 -fno-gcse, these error messages disappeared. This is probably related to a bug in these, rather current, versions of gcc, and other NONMEM subroutines may be compiled incorrectly as well. I'm currently checking the gcc bug archives and testing the latest version, 3.3.2, but it seems the bug hasn't been solved yet. Erik Olofsen Leiden University Medical Center
