Dear all, I've found a bug report for R when installing it on an AIX5.1 system. There's a followup (number 4) that comments a segmentation fault on R when quitting "q()". I'm using a newer version of R but on the same operating system and I obtain the same error. There was a way to solve this problem? Best regards and thanks, --

In version 3.6.1p1i such variables are visible to the user (as expected), but since 3.7p1 they are not... Is this the expected behaviour?

Hello, I am working in a project on a parallel programming language. I want to base our language on Java or C/C++. But Java is preferred. Many similar projects adopts a source-to-source methodology, e.g., Berkeley UPC(using Open64), Titanium, and Rice University's Co-array Fortran. They output C code with calls to the runtime. I think there are at least three reasons: 1) using C as the
