If this is not considered to be safe, then I guess my message can be seen as a
heads-up:
If R_ReleaseObject ever does something that is not safe after the R engine has
shut down, you will start to see crashes from packages like “minqa”.
In FastR, we ended up adding a global flag that disables par
Calling R_ReleaseObject in a C++ destructor is not reliable - it can be
bypassed by a non-local return, such as an error. Generally in R one
cannot use C++ destructors reliably for anything that the R runtime
wouldn't do on its own in case of a non-local return.
