Doing any mathematical operations in light's "power" field if there's a letter "W" present crashes Blender. For example try typing +2 or /2 after or before "W" letter. When you delete the letter "W" it works as expected.

@brecht worked on that yesterday, afaik.

However, I can't reproduce the bug. Could you give a specific example that crashes Blender?

Simply select a light (Point, Spot or Area) and type this:

light_math_operations_bug.PNG

And press enter.

It's weird, I can't reproduce this issue. Not even in todays buildbot build (with the same hash).

Works fine here on macOS.

Seems like the issue is happening only on Windows?
