Just tried out the gcc4 no optimizations r25000 on a Celeron 400Mhz. Ran fine for 2 hours, upon shut down tracker crashed. Then I put a firewire card in and did eventually have a KDL, *but* couldn't reproduce it on further tries. However, I found that opening deskcalc, creating a replicant, and then deleting that replicant caused tracker to crash. This was very reproducible with or without the firewire card. I tried a gcc2.95 version of r25042 and did not have this problem. Curtis
