6946056: assert((intptr_t) sp()<=(intptr_t) result,"result must>=than stack pointer"), frame_x86.cpp:295
Summary: frame::interpreter_frame_monitor_end() will spuriously assert for a frame that spans 0x80000000. Cast values to intptr_t* (rather than intptr_t) so that an unsigned pointer compare is performed.
