[drlvm][exception] With JVMTI enabled ExceptionCatch event makes VM to crash in release mode

                 Key: HARMONY-5329
                 URL: https://issues.apache.org/jira/browse/HARMONY-5329
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
         Environment: winx64
            Reporter: Gregory Shimansky
            Assignee: Gregory Shimansky

Three tests from jdktools that call a method which throws an exception crash in release mode:


The crash happens when transferring control from the method with exception to invoke_managed_func
stub. Return address from the stub back to C code is overwritten with garbage. This happens
because no memory is allocated for exception_catch_callback function to operate in the stack.
All register context is restored for this function, including RSP, on its prologue this function
dumps some registers into stack space called shadow memory, and in this way overwrites return
address in the stack.
