[BUG] UOClassic: Popout script editor crashes and becomes unusable #188

Closed gdavis closed 2 years ago

gdavis commented 2 years ago

Summary On UO Outlands, if you use the popout script editor, and let a script run for a long time, the editor pane of the popout window will crash and you will be unable to edit code until you restart the client.

Steps to Reproduce

  1. Open UO Classic on Outlands
  2. Open the popout editor for a script. Use a long running script, usually around ~20 or so the issue will occur. I was using this script for lumberjacking, but happens for any script as I've been able to consistently reproduce.
  3. Wait
  4. Observe the editor pane will eventually crash with the following exception:
See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

After this exception, the editor window will look like this and be unusable: ScriptEditorCrash

markdwags commented 2 years ago

Based on testing, it appears this issue may only be happening on the Outlands compiled version. I ran local tests for an hour with no errors, but another tester using the Outlands version had an issue. I'm going to close this as they've been made aware, it can be reopened if it can be replicated in the main version.
