Summary0001097: Mixing effects through busses is causing me huge clipping.
DescriptionWhen I run ladspa effects through busses, I get huge clipping anywhere from +50 to +120. The clipping seems to increase over time. The easiest way to try to reproduce this is to run a track through a bus with an effects plugin and change song positions a whole bunch of times until it clips eventually. I'm on a 32 bit FC4 system with an AMD64. I switched to a 32 bit system because I thought if I switched from a 64 bit to a 32 bit system the clipping would stop. It didn't. I've even changed from GCC 4.0.1 to GCC 3.4.4 thinking that maybe GCC 4.0.1 miscompiles ardour. It still clips.
    I had to do some code tweaks, but I got the old ardour-0.9beta29 to compile an work well on this system. It doesn't clip at all, and I'm running a full almost 13 track 2 bus session. It was compiled with GCC 4.0.1. The old release also didn't clip on my 64 bit FC4 OS. Please help, or at least point me to an area of the code that I can tweak on so I might try to create some kind of patch. Thanks.

My bad. It looks like I miscompiled either freeverb from cmt (specifically denormals.h wasn't working right) or ladspa. This issue can be removed. Sorry..
