> I am debugging some crashed code that crashes outside of BEGIN_RAISE_AREA - END_RAISE_AREA region, but in VM code. In this case crash handler when it tries to print the stack shows the following:
> VM attached threads:
> java: /home/gregory/work/64/trunk/working_vm/vm/vmcore/src/jni/jni_utils.cpp:779: bool ensure_initialised(JNIEnv*, Class*): Assertion `!is_unwindable()' failed.
> Aborted (core dumped)
> and dies without printing stack for any thread. This happens because crash handler tries to execute some of VM code that executes
> ASSERT_RAISE_AREA (e.g. in ensure_initialised). Since the area is outside of RAISE, this assertion fails. Stack dump for the crashed process looks like this:
