[issue42889] Incorrect behavior of Python parser after ast node of test program being modified

New submission from Xinmeng Xia : The following program will lead to a incorrect behavior of Python parser. We change all variable to integer( forcely transformed to string) via ast.NodeTransformer. Then we compile the new code and execute it. It's surprising that code like "1=2; print(1)"

[issue42886] math.log and math.log10 domain error on very large Fractions
