        * wrapper.c (gdb_value_assign): New function.  Longjump-free
        version of value_assign.
        (wrap_value_assign): New function. Wrapper for value_assign.
        * wrapper.h: Add declaration for the above.
        * varobj.c (varobj_set_value): Use gdb_value_assign, not
        value_assign which can longjump.  Do not change varobj value if
        assign fails.
