Thank's for the help.

By creating two methods initialize/terminate using 
Runtime.initialize() it's crashing with this strange error.

I looked at the core.runtime source file and I saw a C binding 
for thoses one :

https://github.com/dlang/druntime/blob/master/src/core/runtime.d#L36

/// C interface for Runtime.initialize, returns 1/0 instead of 
bool
extern(C) int rt_init();
/// C interface for Runtime.terminate, returns 1/0 instead of bool
extern(C) int rt_term();

Any idea how can I call them ?
