In java the compiler complains about uncatched exceptions.

Other things that can throw exceptions error anyways.

Foo* p = new (std::nothrow) Foo();
'p' will equal 0 if we are out of heap memory.
What happens if we are NOT out of memory but Foo's constructor throws? Will that exception be "masked" by the nothrow version of 'new' and 'p'...
