Dunno if it helps anyone, but a check of local builds lying around shows the issue in
R version 3.0.2 Patched (2013-11-19 r64260) -- "Frisbee Sailing" but NOT in R Under development (unstable) (2013-11-11 r64196) -- "Unsuffered Consequences" So, it seems that either we introduced a change during that period or the build tools changed. Those builds might not be entirely clean, though. As for C compiler, my current setup has Peters-iMac:~ pd$ ls -l `which gcc` -rwxr-xr-x 1 root wheel 14224 Oct 29 18:10 /usr/bin/gcc Peters-iMac:~ pd$ gcc --version Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1 Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn) Target: x86_64-apple-darwin13.1.0 Thread model: posix On 23 Apr 2014, at 08:39 , Dan Tenenbaum <dtene...@fhcrc.org> wrote: > Hello Simon & Co., > > On R-3.1.0, Mavericks build: > >> 1980000020L + 222000000L > [1] -2092967276 > > On R-3.1.0, Snow Leopard build: > >> 1980000020L + 222000000L > [1] NA > Warning message: > In 1980000020L + 222000000L : NAs produced by integer overflow > > A bug, perhaps? > > Mavericks sessionInfo(): > > R version 3.1.0 (2014-04-10) > Platform: x86_64-apple-darwin13.1.0 (64-bit) > > locale: > [1] en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_US.UTF-8 > > attached base packages: > [1] stats graphics grDevices utils datasets methods base > > Snow Leopard sessionInfo(): > > R version 3.1.0 (2014-04-10) > Platform: x86_64-apple-darwin10.8.0 (64-bit) > > locale: > [1] en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_US.UTF-8 > > attached base packages: > [1] stats graphics grDevices utils datasets methods base > > Thanks, > Dan > > _______________________________________________ > R-SIG-Mac mailing list > R-SIG-Mac@r-project.org > https://stat.ethz.ch/mailman/listinfo/r-sig-mac -- Peter Dalgaard, Professor, Center for Statistics, Copenhagen Business School Solbjerg Plads 3, 2000 Frederiksberg, Denmark Phone: (+45)38153501 Email: pd....@cbs.dk Priv: pda...@gmail.com _______________________________________________ R-SIG-Mac mailing list R-SIG-Mac@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-mac
