That library is used by Xcode (or LLDB) to record backtraces of threads, so
that the debugger can later show the stack that invoked an async call.

I ran into a crash in that library once, and was told it was an Xcode bug. You
should probably post this one in a bug report to Apple.

You can work around the problem by turning off backtrace recording in the
scheme editor.
