Comment (by jeremyhu@…):

 Ah, ok.  thanks.  I was heading back to thinking this was a compiler bug,
 but I'm glad to see it is a project bug and with a fix too!  qt4-mac is in
 the middle of compile here, but I suspect it'll finish up sometime
 tomorrow to allow me to test the change and commit if someone else doesn't
 beat me to it.
