Thanks for all your guys responses! It is amazing to get so many answers in
a few minutes! My package needs to handle the shared memory so the
finalizer does cause memory leaking. The Ex version should be my solution
for that. Thanks for all your help.

Use R_RegisterFinalizerEx in your C code. See
https://cran.r-project.org/doc/manuals/r-release/R-exts.html#External-pointers-and-weak-references
This still gives you only "best effort"; for anything stronger you
would need a different approach.
In general, finalizers should only be used as a ba

Hi all,
I found that the finalizer of the externalPtr is not called when R is
quitting. However, manually calling GC() works fine. This behavior is
observed on devel R 2020-04-02 r78142 on Win and R 3.6.3 on Ubuntu. I make
