-# 重现问题
-
-> 这个在运行py脚本或者gdb运行时不会出现。
-> 
-> 只有单独使用`cminusfc`生成可执行文件会出错。
-
-- 构建`cminusfc`
-
-- ```
-  $ # at path `2022fall-compiler_cminus` 
-  $ cd tests/3-ir-gen/testcases/lv3/
-  $ cminusfc complex4.cminus
-  terminate called after throwing an instance of 'std::out_of_range'
-    what():  basic_string::erase: __pos (which is 18446744073709551615) > this->size() (which is 8)
-  [1]    22357 IOT instruction (core dumped)  cminusfc complex4.cminus
