Description
_try_compile function fromdis module firstly tries to compile given source string with'eval' mode and, if exception is occured, catches it and tries again with'exec' mode. These actions lead to a long chained traceback if given string contains syntax/indentation error, because this string gets refused bycompile in both'eval' and'exec' modes.
All functions/constructors fromdis module that use_try_compile and accept source string as an argument (dis,get_instructions,code_info,show_code,Bytecode) are showing this behavior:
