Frequent "Invalid pointer dequeued from free list" crashes in-game

In macOS build 112209, I see frequent crashes of the main thread due to an invalid pointer dequeued error. The code that causes the error seems to vary in the stack traces. So far, it has happened during:

• crom::RasRenParticleGroupCollection::createGroup
• crom::RasRenVirtualTextureEngine::forcePageResident
  
• MaterialLibrary::getFrozenMaterialData
• crom::ras::GLTexture::bindTexture (happens from event loop instead of main thread)

I'm attaching 4 crash reports with stack traces.

Meant to put this in the Mac & Linux sub-forum if a moderator gets a chance.

Still seeing the problem on macOS build 112214. Happened especially frequently during a 5 player FFA on the Dedicated Community Server on TheEffectTheCause's Broad Walk FFA map. Attaching game log and stack trace with times in USA CDT.
