Hi all,
I am not able to export an ALTREP object when `gctorture` is on in the
worker. The package simplemmap can be used to reproduce the problem. See
the example below
```
## Create a temporary file
filePath <- tempfile()
con <- file(filePath, "wrb")
writeBin(rep(0.0,10),con)
close(con)
library
Thanks for the report. Will look into it when I get a chance unless
someone else gets there first.
A simpler reprex:
## create and serialize a memmory-mapped file object
filePath <- "x.dat"
con <- file(filePath, "wrb")
writeBin(rep(0.0,10),con)
close(con)
library(simplemmap)
x <- mmap(filePath,

I found that also; fixed in r79386 in the trunk. Will port to R-patched
shortly.
