ADDITIONAL OS VERSION INFORMATION :
Apple macOs Sierra - 10.12
A DESCRIPTION OF THE PROBLEM :
Running IntelliJ IDEA 2016.3 EAP builds under the newly released macOs Sierra OS seems to crash intermittently. This doesn't happen all the time, but seems to be in response to certain actions within the application - tho at this time I've noticed exactly what I'm doing to trigger the crash.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
I'm not sure... as yet I've not isolated just what combination of keystrokes when editing code is triggering this.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
No core JVM crashes.
ACTUAL -
Core JVM crashes.
