R 64 on Intel Mac check problem

many thanks for the response. I tried compiling without optimization and it still gives me the same problem. Would you think it is something related to the package? Could it be that I should use another version of the particular package than the one included? Or could it be something with the way the results are compared? Would you suggest I can trust this version of R for performing the statistical analysis I am after?
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.)

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. I am doing this so I can run an analysis that
requires
1.6 gB of memory allocation and would not run on 32 bit version of R as
I
was advised and experienced. I have installed gcc 4.2 and gfortran 4.2 from the available sources on
the
web page and am using the copy and paste guide on the page. Now everything seems to be going fine until the point where the R
packages
are tested. In particular when the regression tests are run I get the following. running regression tests running code in 'reg-tests-1.R' ...\c OK running code in 'reg-tests-2.R' ...\c OK comparing 'reg-tests-2.Rout' to './reg-tests-2.Rout.save' ...\c 3756c3756 < The decimal point is 1 digit(s) to the right of the | ---

make[2]: *** [test-Reg] Error 2

Would any of you be able to point me to what is the reason for this?
thanks,
