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.
