For avoidance of macros, how about something like this:
class MemCounter {
private:
int new_called;
public:
bool checkNewCallsEq(int N) {
#if !__has_feature(address_sanitizer) && !__has_feature(memory_sanitizer)
return new_called == N;
#else
return true;
#endif
}
};
MemCounter globalMemCounter;
#if !__has_feature(address_sanitizer) && !__has_feature(memory_sanitizer)
void* operator new(std::size_t s) throw(std::bad_alloc) {
...
}
#endif
And then in the individual tests:
assert(globalMemCounter.checkNewCallsEq(0));
And then if we want to be even more fancy later on, the MemCounter objects
could be set up to count only within a scope by allowing them to register with
each other to listen for these events. That seems like it'd be beneficial for
at least
`utilities/memory/util.smartptr/util.smartptr.shared/util.smartptr.shared.create/make_shared.pass.cpp`,
and possibly others.

Do MSan and ASan have hooks that we could use to implement these checks when
they're enabled?
