>
> In ThinClientRegion::executeFunctionSH(), the address of a stack variable
> (the result collector lock) is passed to the workers. If an exception occurs
> with any of the workers, the function will return, causing the stack variable
> to be destructed. Since the workers have the raw address, it is now a
> dangling pointer situation.
