[Flightgear-devel] My day for segfaults...
Firstly, can I say that with OpenAL, and Erik's tip for .openalrc I get much
better sound quality from a SoundBlaster Live! and a 5.1 speaker setup.
However, if I exchange frequencies on com1, and then swap them back again, I
get a segmentation fault. I know Dave Luff reported a problem with ATIS, but
I understood that Curt had submitted a fix. This seems to be something to do
with deleting a sound sample.

Jonathan, I believe I fixed this one today ... Curt.
