System Information

Short description of error
After grooming, switching from particle edit mode to edit mode causes blender to crash

Exact steps for others to reproduce the error

open blend file
enter particle edit mode using tab menu
brush hair strands ( If this is not done the bug does not appear )
press tab a few times to toggle between particle edit mode and edit mode.
crash to desktop

I get the following error from stderr

Cannot reproduce here.

Does this also happen with the latest build from builder.blender.org (and updated GPU drivers)?

But it is not Nvidia GTX specific. It also happens on integrated Intel HD graphics.

just a shot in the dark, but does this happen with the --threads 1 commandline option as well?

@Sergey: one for you?

Yes, just tested it: it also happens with the --threads 1 commandline option.

Hi Sergey,

Thanks for the fix, it works between toggling particle edit and edit mode (TAB).

But now it crashes when toggling between object mode and edit mode. At least on my end. :)
Let me know if I should provide more info.
