    [fix] fix the problem that using tsan to compile，BE will stack overflow when start (#8904)
    
    Currently TSAN can only be compiled using CLang, not GCC.
    And when compiling with -o0, stack overflow occurs at startup, issue #8868.
    A function definition will be reported missing at compile time, the file provided in PR #8665 is required.
