        Hi!

        We have found a lib system_kernel.dylib  crash, only in ios12

        It  affects a large group of our users.

         

        Is it a known issue? How can we fix it?

         

        Thanks!

          There’s nothing kernel-specific about this crash.

          Exception Type: SIGABRT

          This indications that your program crashed because something called abort.

          Thread 14 Crashed:
          0  libsystem_kernel.dylib  … __pthread_fchdir + 32

          This shows the backtrace of the thread that called abort.  Frame 0 seems like you have a symbolication problem (is this an Apple crash report, or a third-party one?).  However, the other frames are consistent with you running a work on a dispatch queue (frame 7) and that work throwing an unhandled C++ exception (frames 6 through 2).

          Unfortunately it’s hard to narrow this down further because C++ exceptions don’t produce a Last Exception Backtrace section in the crash report (see this thread).
