About A8 StringAppend

I think the mode cs: ci can not pass test, it will show 9 taintflows in output.Anyone have a good idea about optimization?

I've finished A8. However, I didn't met the problem you mentioned.

Maybe you can try to change the "Type" field of "TaintObj" according to the rule as shown below. After I changed the "Type", the test was passed and I succeeded in passing the oj.
