System Information
system-info.txt

Blender Version
Broken: blender-2.80.0-git.1a865b4ff01-windows64
Worked: none 2.8

Short description of error
Moving keyframes makes some rigs very unstable, with flickering and often resulting in a crash. Renders and baking of frames give out of sync results with unusual stretching of bones.

Exact steps for others to reproduce the error
simply move a key frame, only crashes when several bones are keyed.

Cant get it to crash, but can confirm the flickering.
@JoshuaLeung , @Sergey : have an idea?

@lichtwerk, can not reproduce the crash, but maybe i'm doing something wrong. What are the exact steps to crash this file? Also, mind testing with -t 1 command line argument?

@Sergey: -t 1 seems to solve the issue

What I did:

open file
deselect all bones
select a couple of bones in the spine
Timeline > Dope Sheet Summary > select right key
grab, move left and right --> flickering (might take some wiggeling, but should eventually show up...)

edit: got a crash, too

something with the FCurve bezt pointer magic in fcurve_eval_keyframes()?
