Thank you!

$ type a.d
import win32.windows;
import win32.mmsystem;
import std.stdio;
import core.thread;

extern (Windows)
void waveInProc(in HWAVEIN handle, in uint message, in DWORD instance, 
in DWORD param1, in DWORD param2)
{
     if( !thread_findByAddr( GetCurrentThreadId() ) )
         thread_attachThis();
     if( !_moduleinfo_tlsdtors_i ) // avoid duplicate calls
         _moduleTlsCtor();

     int[] a;
     int[] b = a.dup;
}

$ bud a /Ldetailedmap -g -full
