> Segmentation fault
> If to remove the "synchronized" modifier from the "test()" method declaration, the test passes.
> On SUSE9 Linux em64t the crash does not depend on the "synchronized" modifier: it just crashes with the wording:
> Segmentation fault

> The attached test is the slightly modified smoke test stress.Stack.
