...ore extensive tests before deciding if
this can be ported to the release branch for R 3.5.0. Should know in a
day or two.
Best,

Objects not gc'ed due to caching (?) in R's S3 dispatch mechanism
Hi,
I initially opened an issue in the R6 repo because my issue was with
an R6 object. But Winston (thanks!) further simplified my example, and
it turns out that the issue (whether a feature or a bug is yet to be
seen) had to do with S3 dispatching.
The following example, by Winston, depicts the issue:
print.foo <- function(x, ...) {
cat("print.foo called\n")
invisible(x)
}

This has nothing to do with printing or dispatch per se. It is the
result of an internal register (R_ReturnedValue) being protected. It
gets rewritten whenever there is a jump, e.g. by an explicit return
call. So a simplified example is
new_foo <- function() {
e <- new.env()
reg.finalizer(e, function(e) message("Finalizer called"))
e
}
bar <- function(x) return(x)

help with gotoExitingHandler(R_NilValue, call, entry); . Implementation of error handling internally
...xt and end context directly, so instead what I do is call R_ToplevelExec, grab the global context inside the function, install my own handler that I don?t set to be a calling one, pretend this context is a CTXT_FUNCTION.
Eventually I get to jump fun, so that I can later on grab the condition from R_ReturnedValue.
This works well in the ? not simple error ? case, i.e. if I call stop( simpleError(...) ), but with simple errors, i.e. calls to Rf_error internally or bare calls to stop( "vvzvz" ) I can?t access the error.
And this boils down to this call:
gotoExitingHandler(R_NilValue, call, en...
