"""Simulates a Tesseract crash when asked to run OCR
|

It isn't strictly necessary to crash the process and that has unwanted
|
|
side effects like triggering core dumps or error reporting, logging and such.
|
|
It's enough to dump some text to stderr and return an error code.
|

Follows the POSIX(?) convention of returning 128 + signal number.
