I have inherited a build of R. We compile R from source and then use a custom web application to allow users to enter R statements and render the output (it's kind of like RStudio although the UX is quite different).
Things were going fine until I tried to upgrade to R 4.1.x. The build succeeds, but I get the following segfault when I make qplot (ggplot2) calls: *** caught segfault *** address (nil), cause 'memory not mapped' Traceback: 1: .setMask(NULL, NULL) 2: resolveMask.NULL(NULL) 3: (function (path) { UseMethod("resolveMask")})(NULL) 4: grid.newpage() 5: print.ggplot(x) 6: (function (x, ...) UseMethod("print"))(x) I am not an R developer, so I don't really know how to read this. I am wondering if this is a known issue or if anyone has any suggestions. Here's some things I've tested: - I get the same segfault in R 4.1.0 and R 4.1.1. I do not get this error in R 4.0.4 or R 4.0.5. - The problem appears to be specific to the (graphics?) features of R that ggplot2 uses. I do not get a segfault if I do a generic `plot(c(1,2,3))`. - I have tried versions of ggplot2 3.3.3 and 3.3.5. - The traceback points to files that were introduced in this commit https://github.com/wch/r-source/commit/16755bcddffe0cb4238d8a4979387d92b93a8324#diff-5c63f74229830cdde7886a50bf06dafcdf1d5b3d42cfa06b26814876e58c5ab0 I am not an R user or R developer so I'm a bit stuck here. I would be happy to give the output of any commands. If anyone has any suggestions then please let me know! Thanks!
