[Rd] bug report: nlme model-fitting crashes with R 3.4.0

[Langbehn, Douglas]

lme() and gls() models from the nlme package are all crashing with R.3.4.0. Identical code ran correctly, without error in R 3.3.3 and earlier versions.  The behavior is easily demonstrated using one of the examples form the lme() help file, along with two simple variants. I have commented the errors generated by these calls, as well as the lines of code generating them, in the code example below.

As of today, this bug had not been reported on the R Bugzilla page. I could not submit this report directly to the page because I am not a member, and , as explained in the "Reporting Bugs" link from the  R home page, membership has now been closed due to spamming problems..
