Worked: (optional)

Crashes when extruding edges in edit mode with snap setting turned on

  1. Create a sphere, add to it Sub surf modifer, aplly it.
  2. Add new plane .Turn edit mode.
  3. Select 2 vertex or 1 edge .
  4. Turn on snapping ( to faces )
  5. Extrude few or more times edge on the sphere with snapping to the sphere. It will constantly crash.
    On the sphere it crashes not so often ( maybe need around 20 times to extrude (to make crash ) . On more dense mesh (complex dynotopo head around 500 000 tris) crash is more often ( almost every extrude , 1 or 2 enough to make a crash).
    If I turn off snapping , then all fine, no crashes.
    Thanks for your work , you are awesome =) Good luck.
    Also here is simple file with an explanation ( Just go in edit mode and extrude)

Confirmed after a bit of trial and error, MSVS2017, Windows 10 debug build, this information might help.

Hi, I have changed description a little bit and added small and simple .blend file.
There also notes (grease pencil) in blend file , I hope it will help to reproduce this bug. I do not know what I need to add else to description to help you find error . I hope now you have enough information. Thanks and good luck.

(painfully) managed to reproduce the crash once, but must admit I’m a bit puzzled by the ASAN backtrace…

==28350==ABORTING

Smelling some COW issue again, as if BMEditMesh used in raycasting code was not the same as the one used to generate the looptris, but rather shallow COW-py of it... Still investigating.

(painfully) managed to reproduce the crash once, but must admit I’m a bit puzzled by the ASAN backtrace… ```lines=20 ================================================================= ==28350==ERROR: AddressSanitizer: heap-use-after-free on address 0x61d0008b7488 at pc 0x555d1da4f094 bp 0x7ffc77d5e990 sp 0x7ffc77d5e988 READ of size 8 at 0x61d0008b7488 thread T0 -
