treeModelSortConvertIterToChildIter produces invalid iterators #159

Open glguy opened 8 years ago

glguy commented 8 years ago

It seems that treeModelSortConvertIterToChildIter produces iterators that fail this check treeModelSortIterIsValid and result in segmentation faults when being used.

I've been unable to successfully sort a TreeView using code from the demo directory or examples I've found online.

I'm using GTK+ version 3.18.9 installed via homebrew on OS X 10.11.3, GHC 7.10.3 with current versions of the gtk3 package dependencies.

~/Desktop/gtk3-0.14.2/demo/treelist
$ ./treesort

Segmentation fault: 11

This problem might be OS X specific. I found that the demo worked when I tried it on an Ubuntu machine.
