The function frame::oops_do_internal (in runtime/frame.cpp) tests the non-product option CrashGCForDumpingJavaThread; when true, an attempt is made to cause a segfault by writing to a NULL pointer. Since such a write invokes undefined behavior, anything may happen there. Better would be to use os::signal_raise, rather than writing to a NULL pointer.
