Maybe you can try --ffast-math on ldc.

Sounds like what you want is ASAN? You can use it with plain C or

Hello.
I have dub dependency which has a `shared static this()`.
In my project, can I run code code before the dependency's

This might work:

I have never used dub, but I know it's now also bundled with ldc2.

Is it possible to use classes, which do not have monitor and

Object can be allocated/deallocated using allocators, but they
are very complex for betterC mode (monitor, mutex, object.d
dependency).
Is anyone aware of a tool which does something akin to the
following:
Given a C-like definition, automatically generate pure C code
with no dependencies.
Input c-struct:
struct Person

int id;
char* name;

Output minimal c-code:
