Can you advise me on where best to add the asan calls?
Offhand, I don't know. It's been maybe 15 years since I worked on it, and a lot
of people have moved things about since then.
Dmitry Olshansky has worked on it very recently, in fact he is

Quick extra note: the function pointer solution is not friendly to LTO, whereas
a weak-linking solution would easily be optimized-out fully with LTO. So that's
something to consider too.
This code should be version'd with:

Yep, I've got fuzzing to work too, so... expect nice blogs "soon". ;-)

Another option is to use a pointer to the asan functions, like:
if (asan_fp)
(*asan_fp)(args...)

Thanks for your work on this. It is important to support such
valuable tools.
One way making such things pretty much cost-free in the olden
days was to trick the linker into

Hi all,
I've added AddressSanitizer [1] support to LDC, and it is able
to nicely catch bugs like this one:
```
void foo(int* arr) {
arr[10] = 1;
}
void main() {
int[10] a;
foo([0]);
}
```
It works for malloc'ed memory, but not yet for GC'd memory. Our
GC pool memory is
