我最近升级了我的工具链，这导致gcovr无法生成任何覆盖率输出。有人能告诉我这是gcovr的问题，还是我的工具链，或者缺少依赖项？
以下是我用来验证的示例/比较：
example.cpp

// Taken from gcovr user guide.
// example.cpp

int foo(int param)
{
    if (param)
    {
        return 1;
    }
    else
    {
        return 0;
    }
}

int main(int argc, char* argv[])
{
    foo(0);
    return 0;
}

gcovr版本：

gcovr 6.0

我得到正确的结果：

$ g++ -fprofile-arcs -ftest-coverage -fPIC -O0 example.cpp -o program
$ ./program
$ gcovr

但是，当使用更新的版本12工具链时：

g++-12 (Ubuntu 12.1.0-2ubuntu1~22.04) 12.1.0
Copyright (C) 2022 Free Software Foundation, Inc.

我得到以下结果：
