Well, it’s hard to say, since it doesn’t happen on demand. I’d have to make a new build and push it out to users to see if the reports stopped coming in.
Do you have some experience that this is a compiler bug, or is it just a guess because it involves exception machinery? I would expect that LLVM’s exception handling is pretty well broken-in by now, considering the volume of Obj-C and C++ code that Apple has shipped using it so far. Which isn’t to say that that couldn’t be the problem, but I don’t want to annoy users by putting out a bunch of releases that apparently are unchanged while I blindly flail about behind the scenes, hoping something fixes it.
Best,
Benjamin Rister
