It must have been the "writing at end of file" bit?
I don't know.
It read like it should work.
The offsets were correct, it just didn't work *shrug*.

What `-g` does that makes this code compile and work with DMD?
I guess it's global sharing. not `tls`.
I forgot to add: this is on Windows, the problem doesn't exist
with linux
I reported a bug here:
https://issues.dlang.org/show_bug.cgi?id=23310
The following code compiles and run fine with LDC, but with DMD
it compiles and then default at runtime
```D
-- app.d
enum Test {A, B, C}
Test test = Test.A;
extern(C) void main()
{
switch(test)
{
default:
break;
}
}
```
```
-- object.d
// empty for now
```

Will fix it.
Of course you shouldn't delete the file like that method is
doing. It should probably

You're probably misunderstanding `mixin`. It does not work like
an eval function at Lisp or

You never change `pageId`. So as far as I can tell, you're
always `seek`-ing to the same position, and you just overwrite
the same piece of the file again and again.
Whoops. I guess I missed the point of the question there.

Of course you shouldn't delete the file like that method is doing. It
should probably reinitialize the FILE* descriptor.

You probably need to flush the output.
That's a good idea. I gave it a shot, and the following doesn't
seem to change anything unfortunately:

You can see that the single write + read version of the code
works just fine:
```
pageData[0..4] = [1, 2, 3, 4]
readData[0..4] = [1, 2, 3,
