[R-SIG-Mac] RGtk2 segfaulting on macOS

[Tom Elliott]

Hi,


The macOS binaries were recently built for macOS, however they're still not quite right. Runing the following ...


library(RGtk2)

gtkHScaleNewWithRange(0, 5, 1)


... leads to a segfault ...


 *** caught segfault ***
address 0x0, cause 'memory not mapped'

Traceback:
 1: .RGtkCall("S_gtk_hscale_new_with_range", min, max, step, PACKAGE = "RGtk2")
 2: gtkHScaleNewWithRange(0, 5, 1)


It's preventing some other packages (notably gWidgets2RGtk2) from building on CRAN, since it's tests are running into the same segfault when running tests (gslider calls gtkHScaleNewWithRange):
https://cran.r-project.org/web/checks/check_results_gWidgets2RGtk2.html



Thanks,


Tom.
