* 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.
