@kbranigan here is the PR. Sorry for the long delay: I messed up myself I've already forked this project with different name but could not fork it again, so I...

@ocornut If you want I can try to investigate concerning the segfaut I caught. I think this is not an issue concerning a particular architecture. I just call valgrind on...
