#pragma operator_new (C++ only)

In IBM® XL C/C++ for AIX® 16.1.0 or earlier releases, #pragma operator_new determines whether the new and new[] operators throw an exception if the requested memory cannot be allocated.

IBM Open XL C/C++ for AIX 17.1.3 does not support #pragma operator_new. The new expressions in IBM Open XL C/C++ for AIX 17.1.3 are instrumented according to the C++ standard requirements, which require that a null check is instrumented if the operator new invoked is declared non-throwing; otherwise, a std::bad_alloc exception must be thrown on allocation failure.
