This looks like a build dependency. I get 3.3.2 (yeah, I know, should upgrade): > (1+2i)/0 [1] NaN+NaNi R-devel, march 24: > (1+2i)/0 [1] Inf+Infi on the *same* machine. The difference is that one is stock CRAN, the other was built locally. So with the toolchain being updated for 3.4.0, this difference would likely go away.
