Thanks for the report, fixed in R-devel and R-patched.

Hi,

I am running into a problem when I use the window<- replacement function in R
3.4.0. It will lead to an error when it is called inside a loop, probably
the result of the byte compiler now enabled by default.

When I turn it off, it works again, as in older versions of R. I tested on Win,
Linux and Mac, and the problem occurs everywhere.

Here is a reproducible example:

z <- AirPassengers

# this works
window(z, start =  c(1955, 1), end =  c(1955, 1)) <- NA

# but this does not
for (i in 1) {
  window(z, start =  c(1955, 1), end =  c(1955, 1)) <- NA
}
# Error in stats::window(x = `*tmp*`, start = c(1955, 1), end = c(1955,  :
#   object '*tmp*' not found

# turning off the byte compiler makes it working again (as in older R versions)
compiler::enableJIT(0)
for (i in 1) {
  window(z, start =  c(1955, 1), end =  c(1955, 1)) <- NA
}

Any help is very much appreciated.

Thanks,
Christoph
