System Information
Operating system: Win10 (Build 17763)
Graphics card: GTX1070

Blender Version
Broken: blender2.8, 2019-02-05, as found on the splash screen

Short description of error
Set "Cycles" as render engine and shading type set to "Rendered". Play an animation after that blender crashes.

Exact steps for others to reproduce the error
1.Open the attached file Smoke.blend
2. Set the shading to "Rendered"
3. play animation

@LazyDodo can you reproduce this?

Hi again,
I could reproduce it with another computer. It´s a laptop HP Spectra x360, I7, 16Gb, 1TB SSD, Intel UHD Graphics 620 and latest version Blender 2019-03-04.

best regards

That is certainly a threading issue. I can have these two call stacks at the same time:

It is trying to evaluate the texture after it has been freed.

I'm not sure at which level there should be a lock. It seems like it should not be possible to call ccl::BlenderSession::synchronize while being in ccl::CPUDevice::thread_render. Could be totally wrong of course.

That is certainly a threading issue.

it has been freed. I'm not sure at which level there should be a lock. It seems like it should not be possible to call `ccl::BlenderSession::synchronize` while being in `ccl::CPUDevice::thread_render`. Could be totally wrong of course.
