Description
Another interesting entry from my nightly analysis report:

New nsk.jvmti failures (from 2008.08.06)
    nsk/jvmti/scenarios/hotswap/HS203/hs203t003
        This test failed due to SIGSEGV on Solaris AMD64 Server VM
        (machine vm-v20z-6) and due to EXCEPTION_ACCESS_VIOLATION on
        Win-AMD64 Server VM (machine intelsdv14). This test is covered
        by the following bug:

            6545967 4/4 sp05t003 failed ResumeThread() due to
                        THREAD_NOT_SUSPENDED

        However, the bug describes a different failure mode.

        Update: I think this new crash mode only occurs with AMD64
            and the -XX:+UseCompressedOops option.

        Last failure on 2008.11.28 with Solaris AMD64 Server VM (machine vm-v20z-12) and Win-AMD64 Server VM (machine intelsdv14)
        Previous failure on 2008.11.26 with Solaris AMD64 Server VM (machine colfax002) and Win-AMD64 Server VM (machine vm-x2200-02)

Better summary:

Summary: Using r12 as temporary register around call_VM trashes heapbase becausecall_VM doesn't always return immediately to following code (eg forward_exception, popframe and early return support).

EVALUATION

Summary: missing reinit_heapbase() when popframe support jumps back into interpreter from C code.
