> While processing signals on Linux, or processing crash on both Windows and Linux, VM crashes again in this code when current thread is not attached to VM (i.e. TLS does not hold VM_thread structure pointer).
> Suggested patch fixes this problem for both Linux signal handler and crash handling code.
> With this patch crash info is successfully printed for pure native thread.
> Some improvements were also made in Linux signal handler for stability and unification.
