        We have a complex applicaton which does a significant amount of networking.  We are seeing crashes on non-English locales, with over 50% coming from systems with a Japanese locale.  These crashes only occur on 10.12 and unfortunately we can not reproduce. None of our code is on the stack of the crashing thread.  Below are 2 different callstacks of crashes, with the first being far more prevalent.  Any ideas?

          It’s very hard to see what’s going on given the format of your backtraces.  Is this their native format?  Or did DevForums munge them?  Either way, it’d be helpful if you re-posted the backtraces with one frame to a line, similar to what you’d see in an Apple crash report.

          Speaking of Apple crash reports, do you have one for this crash?  If not, you should try to get one.  If you post it here I should be able to gather more info from that.

          ps When posting blocks of monospace text (like code or crash reports), use the <> to create a code block.
