This fault has been detected when using Blender (2.80 or maste=
r branch)
Steps to reproduce the error:
1. Start Blender
2. Go to edit mode (press tab)
3. Start Merge vertices tool (press ALT-M)
4. Select any mode (press ENTER)
And a segmentation fault happens.
This has been tested on Mesa 18.2.2, 19.0.8 and 19.3.0~dev.
The root cause is that you have a framebuffer with multiple color slots with
empty slots in between. If there is an empty color slot between the color
slots, all textures after this slot are apparently skipped/discarded.
Our work around is to reuse empty slots with other slots.
