System Information

win 10 64bit
Intel HD Graphics 520

Blender Version

blender-2.80-bf2d0782bc4-win64

Short description of error

In Particle mode 'Tab' key moves to Edit mode 
(I think it's also a bug it should move to Object mode as everyone would expect)
Pressing it again moves to Particle mode. And thats when crash usually happen.

Crash doesn't occur in every case. Sometimes I need to press tab 2 times sometimes 12.

On default Cube with default Particle system crash doesn't happen, so I am attaching my blend file.

SCALP.blend

Exact steps for others to reproduce the error

  1. Open the attached blend file
  2. When in Particle mode press 'tab' key several times.

I can reproduce the crash in 1ee93dc670 after hitting the Tab key a couple times at most with the above .blend file and:

  • Windows 10 Pro x64 (1803)
  • AMD Radeon RX580 4GB with Radeon Software 18.8.1

Attached console output and backtrace from a debug build.

Confirmed on linux as well, see ASAN backtrace below, @Sergey think that one is for you. :)

I realised this crash happens only if the particle system was modified before with the Particle edit mode.
You can reproduce this crash on the startup scene by doing the following:

  1. add particle system to the default cube.
  2. switch particle type to hair.
  3. go to Particle Edit Mode.
  4. anyhow modify the hair (comb, add, cut, anything really)
  5. hit Tab key several times
