Short description of error

Hi @ErickNyanduKabongo ,
I can not reproduce this crash nor any artifacts with my setup (Fedora 28/ GeForce GT 740), even when I previously make the mesh non-manifold.
It works fine here for 2.79a, 2.79b and latest master build of the 2.79series.
So maybe it is something specific to your setup. You probably tested this already with blender's factory-settings loaded, right? Do you have the latest nvidia drivers installed?
build-hashes used that all worked fine within my Linux setup:
8928d99270
f4dc9f9d68
0385b33f0b
(from May 5th 2018) -- Edit 13th May 2018: seems as if I didn't test with this version after all. I must have used the wrong opened blender... sorry!I don't have a windows machine available right now, but next week I will have access to one. If no one else has confirmed your bug till then I will give it another try on windows.

I can repro here (on linux)
Seems to be related to the UNDO refactor.
There are a couple of open/confirmed issues with the UNDO refactor, I'll go over them again and see if these tasks can be merged.
#55051 is pretty similar
@ErickNyanduKabongo : I'm sorry - I used the offical blender 2.79b to test this - I will keep in mind to always check with the latest master in the future. So yes with the current master build I can reproduce the bug as described. Sorry again! But with @lichtwerk the bug report is in good hands ;)
There have just been two fixes regarding sculpt/dyntopo (
5330f1c5d1
,6242940639
)With these changes I cant reproduce this anymore (thanx @Campbell Barton (campbellbarton)! )
So @ErickNyanduKabongo : could you check master build from https://builder.blender.org/download? (pretty sure this should be resolved there) and please report back if this indeed fixes it for you...
Marking as incomplete for the time being...
Yes just I checked and it is working now, meaning that is not crashing anymore but still you have to undo twice before the undo takes place. May be should close this one and open another one with the title " After lasso mask, Blender needs two undo before the undo takes place." ?
Changed status from 'Open' to: 'Resolved'
@ErickNyanduKabongo : yes, that would be good (open other report for doubleundo).
Closing this one then (and thx for reporting back!)
