Created attachment 327190 Test program

With upcoming test program I get...

welinder@lenovo ~/gtkwork/gtk+-3.20.3/tests $ make testcalendar && ../libtool --mode=execute ./testcalendar 
  CC       testcalendar.o
testcalendar.c: In function ‘main’:
testcalendar.c:61:16: warning: offset outside bounds of constant string [enabled by default]
       selector = next + 1;
                ^
  CCLD     testcalendar
colour=rgb(255,0,0)
colour=rgb(46,52,54)        <--- Would you look at that!
colour=rgb(255,0,0)

(The warning is inside code copied from foreigndrawing.c; I think gcc is wrong here.)

I don't see any reason why I should get a different colour just because the style context has been saved.

This is with stock gtk+ 3.20.3

Bug 758442 seems related, but that is claimed to be fixed.
