hack patch

Possible fix for this bug and bug #38668 attached (possibly fixes some others
too). I'm not sure how correct this is, how ASLR affects it etc, but at least
this is a start.

Try to reduce the address space to 8TB. 128TB is only for Windows 8.1 and
Windows Server 2012 R2 [1]. (and linux)
Now, you may ask why xaudio2_7 works on Windows 8.1. Actually it doesn't, and
neither does native dsound when using top-down allocations [2].
Native xaudio and dsound try to pack an address and some data into a single
variable. 43 bits for the address (8TB), 21 bits for data.
Native xaudio2_7 and dsound seems to use similar command queues, based on the
pdbs (in this bug the crash happens at XLFQueueRemove, in [2] LFQueuePut).
