is.na(valid_date) too often true on SGI MIPS (PR#6814)
I'm sorry, but this is completely unreproducible, and the second you say is true you quote as false. d is a list, so can you tell us unclass(d) in both cases? Also, I cannot see those examples anywhere in the R sources so can you please show the actual output you got.
