The following code causes a segmentation fault on my machine:
> library(ragg) > agg_png() > library(grid) > grid.segments(gp=gpar(col=3, lwd=50)) > path <- gTree(children=gList(circleGrob(r=.4), + rectGrob(width=.4, height=.2))) > grid.fill(path, + rule="evenodd", + gp=gpar(col=NA, fill=4)) *** caught segfault *** address 0x0, cause 'invalid permissions' Traceback: 1: grid.Call.graphics(C_fill, path, .ruleIndex(x$rule)) 2: drawDetails.GridFill(x, recording = FALSE) 3: drawDetails(x, recording = FALSE) 4: drawGrob(x) 5: recordGraphics(drawGrob(x), list(x = x), getNamespace("grid")) 6: grid.draw.grob(fillGrob(...)) 7: grid.draw(fillGrob(...)) 8: grid.fill(path, rule = "evenodd", gp = gpar(col = NA, fill = 4))
It also causes RStudio to crash when using the "agg" graphics backend.
