There is another issue #368 reporting EXCEPTION_ACCESS_VIOLATION but it seems to have a different cause. Not sure whether they are related.

Did you set R_USER or R_HOME?

[EHBaozi]

Setting/unsetting R_HOME has no impact, the crash happens regardless.

Where should R_USER point to?

[randy3k]

You shouldn't need to set R_USER. I was just guessing if it could be an invalid R_HOME because you have a non standard installation of R.

[randy3k]

Could you check if #382 fix you case?

[EHBaozi]

It does!

[randy3k]

So it is indeed a R_HOME issue.

Your system somehow has multiple versions of R and RCall got confused when the R_HOME from different versions do not match.

[EHBaozi]

How though? I only have one version of R installed.

[randy3k]

Perhaps the previous installation has left some registry records.

I have the same issue. If I just load RCall, Julia crashes with
EXCEPTION_ACCESS_VIOLATION at 0x7ffc0126d721 -- strlen at C:\Windows\System32\msvcrt.dll (unknown line)

If I run ENV["R_HOME"] = "C:\\Program Files\\R\\R-3.6.1" before loading RCall, then everything runs fine. But I have to do this upon starting each new Julia session, despite rebuilding the package.

• R.home() or R RHOME in the terminal both return the path above, but as a short filename: "C:/PROGRA~1/R/R-36~1.1"
• The only windows registry entry for R points to "C:\Program Files\R\R-3.6.1"
• R is in my PATH

Windows 10, Julia 1.5.1. Could it be a path format problem?
