Hi This appears to be happening (at least) because cairo_pdf() delays initialising a Cairo surface until BM_NewPage(), rather than initiliasing a Cairo surface in BM_Open(), and replayPlot() triggers some activity (set clip region) on the device BEFORE a new page is started (so the pointer to the Cairo surface is null, so BOOM). Not sure yet whether to blame replayPlot() for not starting with a new page op...

...anyone else seeing that ? I would appreciate confirmation from a heavier user of cairo_pdf() that I have not broken anything.

Hi, I wonder if this is expected or I'm doing a wrong thing. pdf() dev.control('enable') library("grid") plot(1) grid.text("A") res = recordPlot() dev.off() cairo_pdf() replayPlot(res) dev.off() *** caught segfault *** address 0x4, cause 'memory not mapped' > sessionInfo() R version 3.3.2 (2016-10-31) Platform: x86_64-apple-darwin13.4.0 (64-bit)
