In the process I installed via CRAN from the menu several packages. One installation, exactRankTests, had a distinct anomaly. A DLL attempt to change FPU control word as seem in the last line of the following listing:
That is not likely a bug in R, it's a bug in some other software on your system, which has changed the floating point precision. It's hard to track down exactly what program did this, and hard to fix. The general strategy for tracking it down is to find the minimal operation that does it (e.g. does it depend on which package you install? Do you get it from a local install instead of a remote download + install, etc.) If you set options(warn.FPU=TRUE) then you'll see the warning more often; without that option, it is suppressed.
