c++ - Very old bug with redefining new/delete
Glad to see that there are many improvements. However, an old bug (since the
first time I used DMC, v8.29 or so) is still there, and is reproducible with
the following simple program:
#include <new>
void* operator new(unsigned size) throw(std::bad_alloc);
int main()
{
return 0;
}
The following lines are in dm\include\new.h, but uncommenting them will
trigger similar errors (so really implicitly declared ones seem to have no
exception specifications):
// Implicitly declared ones
//void* operator new(unsigned size) throw(std::bad_alloc);
//void* operator new[](unsigned size) throw(std::bad_alloc);
//void operator delete(void* ptr) throw();
//void operator delete[](void* ptr) throw();
BTW, the error message is very confusing, since it does not show the exception
specifications:
void* operator new(unsigned size) throw(std::bad_alloc);
^
test.cpp(4) : Error: 'operator new' previously declared as something else
It was declared as: void *C func(unsigned )
It is now declared: void *C func(unsigned )
--- errorlevel 1
