Did you have any update on this? If there is a problem with MinGW-w64 
version, you can (just for experimentation) try UCRT demo build, which 
uses a newer version of MinGW-w64 than RTools 4:

Please note Brian Ripley has added/improved support for cross-compiling 
on Linux for Windows, so that it can be used for diagnosing LTO warnings 
(see NEWS in R-devel and src/gnuwin32/README.compilation). The 
cross-compilers and needed cross-compiled libraries for R itself are 
part of at least some Linux distributions (he tested on Fedora).

Microsoft is giving for free time-limited VMs primarily for testing 
Edge/MSIE, you can run them in e.g. in Virtualbox. As instructed in the 
VM, take snapshots often.

Being able to test R on Wine may be useful, if you figure it out, I 
would be interested to learn more. It is easier to obtain, may be easier 
to automate, and some low-level bugs may be easier to diagnose. Of 
course, for the price of sometimes seeing errors not present on real 
Windows.
