I am seeing a bad binding access error now with the previous release of [reproducible] package on CRAN with devel versions of R. I have done a work around for now in reproducible.
I can manually reproduce this with R-devel on my local machines.
The minimal reprex using R-devel (R Under development (unstable) (2024-03-28 r86224)) is:
lobstr::obj_size(as.environment("package:lobstr"))
# Error in obj_size_(dots, env, size_node(), size_vector()) :
# bad binding access
It appears on Windows 10 and Linux (Ubuntu) systems that I have tested.
