I need `return` for what exactly? Your code still compiles,
and my point is it shouldn't. It sure isn't memory safe.
@safe:
struct MyStruct
{
import core.stdc.stdlib;
int* ints;
this(int size) @trusted { ints = cast(int*) malloc(size); }
~this() @trusted { free(ints); }
inout(int)* ptr() return inout { return ints; }
}
int* gInt;
void f()
{
auto s=MyStruct(10);
gInt=s.ptr;
}
Error: address of variable s assigned to gInt with longer
lifetime
Looks safe to me.
With dmd 2.081.2 on Arch Linux, the code above compiles with no
error message.
Never mind, I forgot to use -dip1000. Ok, cool, so _why_ does it
work as intended now? Also, if I have to remember to annotate
correctly, surely this is a massive hole in @safe dip1000?
