gcc 4.1.1 is current, and I would suggest an update would be a good idea: my tests with gcc4 went a lot better with 4.1.0 than 4.0.3. I have an FC5 dual x86_64 system (hence gcc 4.1.1) with ACML 3.5.0 and Goto 1.06 (I cannot get ATLAS to build on that system). I too get a segfault with ACML (I used the _mp version, but also tried with it confined to a single thread), but not with Goto nor R's internal BLAS. > I do not encounter the segfaults when I compile R with R's built-in > BLAS.
