I would like to avoid using CRAN as a debugging tool. Is there a way to check packages on Solaris? I am using Windows 10.

I had a bug once only arising in Solaris SPARC. I found a forgotten
storage room in the university packed with old stuff, and rescued a
dusty Sun SPARC server. A professor allowed me to attach it in the
department's server room and, surprisingly enough, it worked except
for a fan. Then I installed all the stuff needed with great pain, and
finally found and solved the bug. In fact, it was in Rcpp. So go
figure, I was very sad when the SPARC machine on CRAN died.
But I digress. Now there's just the x86 Solaris machine, so you can
test this in a virtual machine, using e.g. VirtualBox. Or you can try
the Solaris box on rhub:
