short backtrace

Colin McRae Rally 2.0 currently needs a dll override for msadp32.acm, otherwise
the following assertion error is thrown by the built-in version (see attachment
for backtrace):
msadp32.c:228: cvtSSms16K: Assertion `*src <= 6' failed.

The exception is thrown after the long video has been played and the title
screen is resumed.
Curiously enough, the game provides exactly the native library in the
installation directory, so using the override was easy:
[Software\Wine\AppDefaults\CMR2.exe\DllOverrides]
"msadp32.acm"="native"

Using Ubuntu 8.04, winecfg: ALSA HW accel.

Alas, the game is not playable because no background is rendered (street and
landscape are invisible), but that's another bug topic.
