/*
 * The bug (JDK-4525714) is about failing PopAsynchronousTest test.
 * This is another test of the same issue. The bug occurs when trying
 * to walk the stack of a deoptimized thread. We can do this
 * by running in -Xcomp mode and by doing a step which causes deopt,
 * and then a 'where'. This will cause not all the frames to be shown.
