Hi,

While analyzing one of our applications using Adress Sanitizer, I found a potentially serious bug in `host/pc/asiolist.cpp`:

```cpp
static LPASIODRVSTRUCT newDrvStruct (HKEY hkey,char *keyname,int drvID,LPASIODRVSTRUCT lpdrv)
{
  // ...
  lpdrv = new ASIODRVSTRUCT[1]; // L.84
  // ...
}

static void deleteDrvStruct (LPASIODRVSTRUCT lpdrv)
{
  // ...
  delete lpdrv; // L.120 - BUG: should be 'delete[] lpdrv';
  // ...
}

```

Can this be fixed in the next release ?

Thanks,  
Lorcan
