Could you please provide the full sketch code? If the module reboots, please check serial output for the stack dump, then decode the stack dump and paste the result here. Thanks.

listing is very large. I tried a simple example works correctly. At the same time on the core 2.3.0 all fine.
When setting any value for PWM LED starts to flicker slightly, and after some time the module is restarted.
In serial output only:

@llams No MCVE sketch, you didn't specify which pin.
I am using analogWrite() with latest git, and I can't reproduce this (ref: WittyCloud pins 12/13/15).

• You have to set the pinMode to OUTPUT first (not doing it doesn't cause a reset, though).
• There are certain pins that can't be used, e.g.: pin 9 on an ESP12F.
• You have to mind your power supply. For development I use a 5V20A supply (yes, 20 amps) to make sure that any reboots are not due to voltage dips.
  Closing as can't reproduce.
