Hello, I'm a student working on vulnerability detection area. I wrote a program to detect concurrency vulnerabilities, which detected a concurrency double-free vulnerability. The detail of the detected vulnerability is listed next. Can you help verify it? Many thanks. The detail of the detected vulnerability is as followed: The global variable _thread is not protected by a mutex, and these are 3 free operations on the variable. One occurs at line 620 in trcend(), which has been called repeatedly...

Hello, I'm a student working on vulnerability detection area, I wrote a program to detect concurrency vulnerabilities, and there seems to be one concurrency double-free vulnerability. Can you help me varify it? Many thanks. The details of the suspected points are as followed: 1.it's mainly because that the global variable _thread is not protected by a mutex, and these 3 frees of which one in line 620 in trcend() that free all the contents in_ thread might have a double free problem with two free...
