[Bug 47858] x3daudio1_{0,1,2} need ABI corrections

[WineHQ Bugzilla]

--- Comment #4 from Rafał Mużyło  ---
OK, so, I've finally googled the proper way of running gdb on wine (given that
'winedbg --gdb' is useless to me).

If my guess is correct, the outlook (for this bug) is bad.

(gdb) print *(pListener)
$2 = {OrientFront = {x = 0, y = 0, z = 1}, OrientTop = {x = 0, y = 1, z = 0}, 
  Position = {x = 0, y = -4, z = 0}, Velocity = {x = 0, y = 0, z = 0}, 
  pCone = 0x2e422020}
(gdb) print *(pListener->pCone)
Cannot access memory at address 0x2e422020

...and what exactly is my guess ?

Well, as wine doesn't provide xactengine (even though a partial implementation
seems to exist in FAudio), native lib needs to be used.
Now, compare the value of pListener and pListener->pCone...

I believe we're hitting a variant of bug 38668, more exactly, the part
described in bug 41618 comment 5.
This would mean that native xactengine requires native x3daudio.
