[R-SIG-Mac] [External] Rmpfr crashes on Mac

[Dev Chakraborty]

I am using:

RStudio 2021.09.0+351 "Ghost Orchid" Release
(077589bcad3467ae79f318afe8641a1899a51606, 2021-09-20) for macOS
Mozilla/5.0 (Macintosh; Intel Mac OS X 12_0_1) AppleWebKit/537.36 (KHTML,
like Gecko) QtWebEngine/5.12.10 Chrome/69.0.3497.128 Safari/537.36

It is an RStudio issue; the problem does not occur when I run R from the
Console.

Thanks for the suggestion.

Dev
