> > >> I've done some more investigation into the problem, and it is very difficult to pin down. What it looks like is happening is roughly like this: - `p` is an environment and `p$e` is also an environment. - There is a loop. In each iteration, it looks for one item in `p$e`, saves it in a variable `x`, then removes that item from `p$e`. Then it invokes `x()`. The loop runs again, until there are no more items in `p$e`.
The problem is that `ls(p$e)` sometimes returns the wrong values -- it returns the values that it had in previous iterations of the loop. The behavior is very touchy. Almost any change to the code will slightly change the behavior; sometimes the `ls()` returns values from a different iteration of the loop, and sometimes the problem doesn't happen at all. I've put a Dockerfile and instructions for reproducing the problem here: https://gist.github.com/wch/2596a1c9f1bcdee91bb210c782141c88 I think that I've gotten about as far with this as I can, though I'd be happy to provide more information if anyone wants to take look at the problem. -Winston [[alternative HTML version deleted]] ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
