| ============== |
| |
| This check flags uses of default ``operator new`` where the type has extended |
| alignment (an alignment greater than the fundamental alignment). (The default |
| ``operator new`` is guaranteed to provide the correct alignment if the |
| requested alignment is less or equal to the fundamental alignment). |
| Only cases are detected (by design) where the ``operator new`` is not |
| user-defined and is not a placement new (the reason is that in these cases we |
| assume that the user provided the correct memory allocation). |
| |
| This check corresponds to the CERT C++ Coding Standard rule |
| `MEM57-CPP. Avoid using default operator new for over-aligned types |
| <https://wiki.sei.cmu.edu/confluence/display/cplusplus/MEM57-CPP.+Avoid+using+default+operator+new+for+over-aligned+types>`_. |
