On Linux (including IDAaaS), attempting to run the following script will produce a segfault:

from concurrent.futures import ThreadPoolExecutor

import RATapi as RAT

executor = ThreadPoolExecutor()
future = executor.submit(RAT.examples.DSPC_standard_layers)
project, results = future.result()

This is an issue because RasCAL-2 needs long-running code (e.g. RAT.run()) to run outside the main loop, as the main loop is used for handling and updating the GUI itself. It seems to run successfully on Windows (@DrPaulSharp managed to run it okay). If anyone else would like to run the script on whatever devices they have to hand that'd be useful!

Various observations:

• This happens for any of the standard_layers or custom_XY examples but NOT the custom_layers examples which run successfully.
• On DSPC_standard_layers it happens no matter what procedure is chosen.
• From where it crashes, it seems that we enter the C++ code before it breaks; if using a non-calculate procedure, the Running [procedure] message is produced before it segfaults.
