devtools::load_all() doesn't currently work with lme4

[annahuynhly]

Hi, I'm an lme4 author.

Initially I thought there was an issue with lme4, but upon closer check this is only an issue I have when I use devtools::load_all(): lme4/lme4#950

If I run:

> devtools::load_all()
ℹ Loading lme4
Loading required package: Matrix
> fm1 <- lmer(Reaction ~ Days + (Days | Subject), sleepstudy, REML = FALSE)
Warning messages:
1: In initializePtr() :
  subscript out of bounds (index 180 >= vector size 64)
2: In initializePtr() :
  subscript out of bounds (index 180 >= vector size 64)
3: In initializePtr() :
  subscript out of bounds (index 180 >= vector size 64)

This appears to be an issue related to lme4.

However, if I just build the lme4 tarball myself and then do:

library(lme4)
fm1 <- lmer(Reaction ~ Days + (Days | Subject), sleepstudy, REML = FALSE)

There is no error.
