Hi,
This program, compiled with dmd 1.065 under Linux, crashes:
void main() {
Num a = 1;
}
struct Num {
int[] d;
Num opAssign( int v ) {
d.length = 1;
d[0] = v;
return *this;
}
}
It looks like d is not initialized before opAssign() is called.
It doesn't crash if I replace "Num a = 1" with:
Num a;
a = 1;
Is this normal behaviour?
I don't believe the failing code uses opAssign. I believe that is
initialization. In D2 "Num a = 1;" would be initialization or call a
constructor if appropriate and "Num a; a = 1;" would use opAssign. Based on
http://www.digitalmars.com/d/1.0/struct.html I am thinking it does the same
(minus the constructors). So I think this might be a bug with struct
initialization in D1, I don't think you should be able to just assign 1 to
it.
My guess is that it's doing:
a.d[] = 1;
and since d.length==0, that's a no-op.
It shouldn't compile.
