It could be that there is a bug here in AULab (so we should have a look at that).

I'm generally setting the vector size env variable when I run libgmalloc, just to be sure

After fixing a buffer overrun in my AU that I found with Guard Malloc, I ran AU Lab again with Guard Malloc on and loaded my AU. It crashed. At this point I was starting to feel like the problem might lie elsewhere, so I loaded the AUPinkNoise sample AU into AU Lab with Guard Malloc enabled and it crashed in the exact same location. This is running on 10.5.2. I thought that Guard Malloc and vector routines were now friends on Leopard. Are there some other caveats to Guard Malloc that I'm not aware of? If not then I'll file a bug report.
Here is the crash log:
