The backtrace shows the crash happens in dotTclObjv [/src/library/tcltk/src/tcltk.c@243 ]. This looks like a bug that was introduced by commit 78408/78409 about a month ago. I think the problem is that this commit changes 'calloc' to 'Calloc' without changing the corresponding 'free' to 'Free'.
The same commit made the same kind of change to unix/sys-std.c as well. Duncan Murdoch
This has nothing to do with the Windows build or installation. Nothing has changed in the windows build procedure between 4.0.0 and 4.0.1. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
