I have a small program in C that I wanted to add a GUI to, so after looking around I decided to use GTK+. I installed gtk2 using MacPorts (version installed was gtk2 @2.24.18_1+x11).
I am compiling my program with
gcc -Wall -Wextra -pendantic `pkg-config --libs --cflags gtk+-2.0` myprogram.c -lpthread -o myprogram
There are no errors during compilation, but when I run it, after some amount of time I will get random errors appearing such as:
Gdk:ERROR:gdkregion-generic.c:1110:void miUnionNonO(GdkRegion *, GdkRegionBox *, GdkRegionBox *, gint, gint): assertion failed: (y1 < y2) Gdk:ERROR:gdkregion-generic.c:337:void miSetExtents(GdkRegion *): assertion failed: (pExtents->y1 < pExtents->y2) Assertion failed: (ret != inval_id), function _XAllocID, file xcb_io.c, line 529. Fatal IO error 35 (Resource temporarily unavailable) on X server /tmp/launch-7OAilk/org.macosforge.xquartz:0. Assertion failed: (! xcb_xlib_unknown_req_in_deq), function dequeue_pending_request, file xcb_io.c, line 179.
It looks to me like these errors are caused by a bug in Gtk/Gdk/XQuartz, is there any easy way to fix this?
I am running OS X Mountain Lion 10.8.4, XCode 4.6.2, and XQuartz 2.7.4 (xorg-server 1.13.0).
