Using different compilers or self compiled versions of gcc is not really an option for me, because I run a continuous build system here which compiles several millions LOCs in a loop, using ccache and distcc (which needs the same version of gcc on every compile host, and I'm only responsible for half of them). > I had some success with using self-compiled gcc, e.g. the latest 4.1 > prerelease 4.1.2-20070129, but I'm still trying to find out how to be > sure to avoid the problem. We'll see, I hope. Currently I use 4.1.1 > improvements, distro compilers used to be <=3.3 for a long time. > Perhaps you had less problems with FC<6, do you remember? I skipped FC5 and used FC4 before. As far as I remember, link times did not change significantly between the versions. I think, the compiler version was 3.4.x (x=4?). Maybe some improvements can be done by some template usage tricks, so the compiler/linker knows, which symbols/functions are needed?
