Reporting when S3 methods in base/recommended packages are overwritten 
by the checked package. These things are documented in R Internals 
manual, search for _R_CHECK_OVERWRITE_REGISTERED_S3_METHODS_. In the 
source code 
(https://svn.r-project.org/R/trunk/src/library/tools/R/check.R) look for 
the same variable or "use of S3 registration".

In principle, you could check if your package is doing something special 
re S3 methods registration and experiment with that to see when the 
problem disappears. Or you could debug on the R end (build R with debug 
symbols, run the example, connect to R via gdb, print the stacktrace, 
etc, etc.). Or create a minimal reproducible example so that someone 
else could do that, instead. In either case, it would be interesting to 
know the cause to see if the checking could be made more robust.
