[R-SIG-Mac] Problems with R-4.4.2 in MacOS Sequoia with Intel chip

[Gilberto Camara]

Dear Simon 

Since your message last week, I have been trying to reproduce the errors I am finding with R-4.4.2 in an Intel MacMini to build a minimum testable example. I am not succeeding in doing so.

The error is a total collapse of R and occurs in a random fashion. Sometimes calling another package (e.g. “xgboost”) produces the error. Sometimes making a simple operation in a data table leads to error. 

The problem affects only Intel-based MacMinis with R-4.4.2. Running MacMinis with R-4.2.3 work will. All is also well with R-4.4.2 in Macs with ARM, in Windows and in Lunix/Ubuntu and Linux/Fedora. 

One issue I noticed is that the default C++ compiler in MacOS Sequoia is compatible with c++-17, while the one used by CRAN is version c++-14.00.

Do you have any ideas on how to proceed? Any test data set I could use? 

Many thanks 
Gilberto

Just saying "cannot execute my scripts" is not helpful at all - please provide exact output, how it differs between the versions etc. For example, the problem may be in your code or packages used - we have no way of knowing without the necessary additional information.
