crash when moving between stacks (again)

[Björnke von Gierke]

Crashes should always be reported directly to runrev. They always get highes priority. And they can give you a workaround. However, they depend on the crashes to happen on their own machine, so you might need to send them example stacks.

I suggest you contact support with this.
