--- Comment #4 from Cameron Angus <cjangus at gmail dot com> --- Okay this is rather annoying, this reduced repro no longer crashes on a more recent build, but my original code still does, so the underlying bug is still there. I was told by a contributor that the bug appeared to be in the garbage collection, which is why seemingly irrelevant changes to the code would make it appear or disappear. So it seems that whatever has changed in recent builds has also caused this to stop reproducing as is. Can it be investigated on the version originally given? If not, I can recreate a reproduction, but it will take some time.
