.. title:: clang-tidy - cert-mem57-cpp
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
