digitalmars.D.bugs - Class comparison problems
First of all, I'm not an English speaker. So be tolerant of my poor English.
I'm using Win32 compiler v0.135.
I wrote the following code and had some problems:
int main()
{
Object c = new Object;
Object d = null;
if (null == c) {} // Access Violation
if (c == null) {} // Ok
if (d == c) {} // Access Violation
if (c == d) {} // Ok
bit b;
b = (1 == 2); // Ok
b = (c == d); // Compile Error(cannot convert int to bit)
return 0;
}
I'm sorry if these are known issues...
