#2832: possible race condition in LoopControl
Reporter: Roland Haas Status: new Milestone: Version: Type: bug Priority: major Component:
Comment (by Roland Haas):
There’s `alignas` since C++11: [https://en.cppreference.com/w/cpp/language/alignas%5D(https://en.cppreferenc...) though this may not be any different from `CCTK_ATTRIBUTE_ALIGN` and indeed
``` #include <vector>
struct alignas(128) aligned_t { volatile int foo; };
std::vector<aligned_t> test_aligned_vector; aligned_t *aligned;
void foo() { aligned = new aligned_t(); } ```
gives the same warning when compiled with `g++ -std=gnu++11 -c -Wall` (only warns about `new` not about `std::vector` but I suspect that `std::vector` also does not align and only hides the issue because it internally uses a `void*` pointer for its storage).
