[R-SIG-Mac] PCRE JIT compilation error

[Simon Urbanek]

Bryan,

thanks! There seems to be an issue with PCRE2 JIT on Mojave. I have now disabled JIT in PCRE2 which seems to be the recommended fix 

I have built the latest version of R 4.0.0 alpha - it is now available from

http://mac.r-project.org/high-sierra/R-4.0-branch/R-4.0-branch.pkg

as usual.

Thanks,
Simon
