Note that your compiler is not the same as mine (from Xcode 3.0). If it fails without optimization, I would not trust it. I don't know though which it is: http://cran.stat.sfu.ca/with is not a valid URL, and I don't know which instructions you followed (assuming they are somewhere on CRAN). Simon Urbanek is making available quad-arch experimental builds of R-devel, and I suggest you try one of those. (I haven't, but then I have other, reliable, 64-bit platforms and am only doing this to test changes to R.) > many thanks, > georgios > > > On Tue, Mar 25, 2008 at 6:39 PM, Prof Brian Ripley <[EMAIL PROTECTED]> > wrote: > >> I saw this yesterday, on my newly reinstalled iMac (10.5.2), with the >> Xcode compiler + gfortran from R 2.6.2. >> >> It looks very like a compiler bug: if I insert a printf statement in >> stem.c I get the correct answer, and if I compile src/appl/stem.c without >> optimization I get the correct answer. >> >> So, I suggest lowering the optimization level, but the worry always is >> that if you have one piece of code miscompiled there may be others. >> >> On Tue, 25 Mar 2008, Georgios Marentakis wrote: >> >>> Dear all, I have been following the instructions on >>> http://cran.stat.sfu.ca/with the intention to install R with 64 bits >>> support on an 8 core Intel Mac >>> with 6 GB of memory.
