Furthermore, it is set via XSetErrorHandler, not XSetIOErrorHandler ... so we should never be calling into x_init_error_handler from XIOError, and we should never be calling into that handler from within the CFRunLoop.

The above sounds like "sample" misattributing a code address to the wrong symbol because the right symbol has been stripped.  Unfortunately, it takes some sleuthing in the assembly code to figure out the real stack trace, if it's even possible.
