System Information
Operating system: Win10 64bit
Graphics card: GTX 1050 Ti

Blender Version
2.80 a91886e76e 2018-12-19

Short description of error
Blender crashes if you switch material settings "Blend Mode" from [Opaque] e.g. to [Alpha Blend] if you are in Rendered viewport, Engine: EEVEE.

Exact steps for others to reproduce the error
select render: EEVEE
select vieport mode to "Rendered"
select the object you want to change BlendMode
within material settings, goto "Settings"
change "Blend Mode" from [Opaque] to [Alpha Blend]
Blender chrashes a few secs later

if you change BlendMode while in "Solid" or "Wireframe" viewport and now switch back to "Rendered", it works fine

Could not reproduce on b49699b1ec. Does it happen in the default scene?

ok, this is weird. I tried it now at home with a very simple scene. Just a cube with some basic material nodes. This scene was created with a previous version of Blender 2.8
I changed Blend Mode and Blender crashed. I reloaded the scene and just saved it [Ctrl+S] now it seems to work.

The file I got this error the first time was originally created in Blender 2.79. I made a copy and opend it with Blender 2.8 and also saved it in 2.8. The filesize is about 200MB. Maybe there is a compatibility issue between 2.79 and 2.8 files.
I will watch this issue further and try to reproduce it with a more simplier scene.

Can't reproduce this either.

Let us know when you have a nice reproduction method.
