[sldev] audio_update_wind() not protected against NULL gAudiop

[Robin Cornelius]

Hi Guys,

In the latest main stream source, 1.18.1.2 there is a bug that only 
seems to show its head when you compile yourself on linux (anyway no 
idea for windows)

Anyway if kAUDIO_ENABLE_WIND is defined then the function body of 
audio_update_wind() in viewer.cpp:4202 is enabled and if like me you 
have sound issues and have all 3 sound servers disabled in the start up 
script you have a NULL gAudiop.

In the distributed viewer it does not crash this way, and I am not sure 
when and how kAUDIO_ENABLE_WIND gets enabled but it did when i built a 
linux debug build.


a quick fix is to patch line viewer.cpp:4902

from

if (region)

to

if (region && gAudiop)

Regards
