From db442c10391586f007ac060245dc322a38c9b204 Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Fri, 16 Nov 2018 16:27:58 -0800 Subject: [PATCH] sim: Deschedule existing events when destructing an event queue. Other objects in the simulation may try to deschedule their events when destructed, and if they're cleaned up after the event queue is then they might try to deschedule events on an event queue that no longer exists.
