wing fields:
        - Registers: Output of gdb's 'info registers' command
        - Disassembly: Output of gdb's 'x/16i $pc' command
        - Stacktrace: Output of gdb's 'bt full' command
        - ThreadStacktrace: Output of gdb's 'thread apply all bt full' command
        - StacktraceTop: simplified stacktrace (topmost 5 functions) for inline
          inclusion into bug reports and easier processing
        - AssertionMessage: Value of __abort_msg, __glib_assert_msg, or
          __nih_abort_msg if present

        The optional rootdir can specify a root directory which has the
        executable, libraries, and debug symbols. This does not require
        chroot() or root privileges, it just instructs gdb to search for the
        files there.

        Raises a IOError if the core dump is invalid/truncated, or OSError if
        calling gdb fails, or FileNotFoundError if gdb or the crashing
        executable cannot be found.
