Short description of error
I will randomly crash when you press alt + left mouse [and alt+ctrl+left click] on weight paint mode

Exact steps for others to reproduce the error

EDIT:
Seems like this is caused by two modifiers depending on normals "dependsOnNormals" [Displace modifiers (direction set to Normal) in this case -- but can also be reproduced with two shrinkwraps or two waves with the corresponding settings] will destroy the CD_ORIGINDEX layer [which then cannot be found in BKE_mesh_foreach_mapped_vert -- leading to problems later...if any generative modifier follows]:

#68024.blend

if one of the Displace modifiers has its direction changed to something else then Normal, the crash wont happen

ORIGINAL REPORT:

just try to do gradient in weight paint mode [with keyboard shortcut], it will crash randomly sometimes.

I speed up video since it happened randomly

I can't reproduce the problem using the default cube, subdivided a few times.
Please provide simple steps to reproduce the problem. (Preferably from the default cube).

Hmm. I haven't been able to replicate this after several minutes of trying on the default cube. I'm wondering if there's something about your file or system that's tripping you up...

Have you tried resetting to factory settings (in case you have a glitchy addon) and seeing if this persists?
Does the same thing happen in other files (such as the default cube, or other unrelated meshes in other files)?
Are all your drivers up to date?

No, it not work with default cube

It happened when I import model to blender [.fbx/.dae]
I try factory setting it still won't work, it usually crash when I hold Alt then left click to paint

It not crash on all file but some file will

all driver are up to date

model that crash on 2.8 will not crash on 2.79

Can you maybe create a blend file with one of the imported object models that causes the crashing issue? It would help the developers to investigate the issue further if you uploaded the file.

Hi, I have the same problem with the attached file, just try to apply the gradient on weigth tool and it will crash always (this is my first bug report, sorry if this is not the way to do it)

it is a simple file so i will investigate wich is the step that produce this error, however I did not import any asset in the scene as was mentioned above.

I dont know exactly which step could be producing the crash, but I managed to reproduce it consistently in 3 new files so this could help

sorry if the video is too long, i did it exactly as it happened the first time

If you open console before it crash, it show error too.

Seems like this is caused by two Displace modifiers (direction set to Normal) will destroy the CD_ORIGINDEX layer [which then cannot be found in BKE_mesh_foreach_mapped_vert -- leading to problems later...if any generative modifier follows]:

#68024.blend

if one of the Displace modifiers has its direction changed to something else then Normal, the crash wont happen
