Ticket details:
According to cppreference, the function std::aligned_alloc is apart of C++17.
When trying to compile the example code found at that page, the following
compilation error occurs:
src code
1. #include <cstdio>
2. #include <cstdlib>
3.
4. int main()
5. {
6. int* p1 = static_cast<int*>(std::malloc(10*sizeof *p1));
7. std::printf("default-aligned address: %p\n", static_cast<void*>(p1));
8. std::free(p1);
9.
10. int* p2 = static_cast<int*>(std::aligned_alloc(1024, 1024));
11. std::printf("1024-byte aligned address: %p\n", static_cast<void*>(p2));
12. std::free(p2);
13. }
compilation output
