Would you consider the following patch to eval.c to allow compatibility
with RCC? (It's in the applyClosure function.)

RCC (http://hipersoft.cs.rice.edu/rcc/) is a static compiler for R we're
working on at Rice. It compiles R scripts into dynamic libraries that can
be loaded from within R using the dyn.load function.
This change enables compiled R code to be executed while retaining full
correctness; i.e., inspection and modification of closures generated by
RCC will work exactly as in interpreted R. This patch does not change
the existing implementation in the default build; when enabled, it should
not affect the evaluation of any R code except code compiled with RCC.
