[Bug runtime/14546] DWARF unwinder can corrupt probe memory

http://sourceware.org/bugzilla/show_bug.cgi?id=14546

--- Comment #3 from Mark Wielaard <mjw at redhat dot com> 2012-09-05 18:17:23 UTC ---
Issue is this in unwind.c, the sizes don't match up and some extra stuff (18
bytes) gets written after cie_regs, which is at the end of unwind_state, which
is at the end of unwind_context.

        /* Store initial state for use with DW_CFA_restore... */
        memcpy(&state->cie_regs, &REG_STATE, sizeof (REG_STATE));
