Thank you very much, Aaron.
This is indeed a bug, and it looks that I had caused it when
introducing the internal str_parse() utlity.
It's too bad this is so close before release of R 3.4.3 and the
fix to the bug is not trivial (not very hard either) such that
it most probably will not make it into 3.4.3.
