Summary: ALL: crash on windows when using internal MIDI

Initial Comment:
Just compiled ScummVM from CVS. ScummVM 
crashes right after starting any game (except for 
Sam'n'Max) with a null pointer acces. Here are some 
details:
SDL 1.2.6 from CVS
MAD 0.14.2b (latest tarball)
ScummVM from CVS
All checked out and compiled today with MSVC 7.
When I start ScummVM with "-e windows" everything 
works.

Here are some more details of the crash:
Crash in fmopl.cpp line 1002:
(ams = ams_table[(amsCnt+=amsIncr)>>AMS_SHIFT];)
ams_table is 0x00000000

Stack Trace:
SoundMixer::onGenerateSamples(...)
SoundMixer::mix(...)
MidiDriver_ADLIB::premix_proc(...)
MidiDriver_ADLIB::generate_samples(...)
YM3812UpdateOne(...)

If you need more info just tell me. I'm also ocassionally 
on IRC as Dark-Star.

Happy bughunting ;-)
