Hi, here's a fix of another double free bug. DataDecoder::get_string_raw() shouldn't free the allocated string. It will usually be freed by the the callers String_var - and this would be the second time this memory area would be freed. CRASH!! DataDecoder::get_string_raw_stl() only uses a C char pointer and so should now free it even on a failed DataDecoder::get_string_raw() evaluation.
