I notice the fuzz-test script already sets a bunch of environment variables for memory checking, so I'm not sure if valgrind would really add anything. How extensive are the memory checks turned on by the fuzz-test script? Would valgrind be a useful addition, or would it be mostly redundant? Thanks, EvanI'm not sure either, but out of the 3 problems reported by valgrind that I just fixed: - 1 was writing outside of allocated data (which the canary checks may have picked up on) - 2 were reading/displaying/branching-based-upon uninitialized data (which I don't expect other types of checks would spot) Martin
Basic support added in revision 44024, so it's there if people want to use it. I don't know if it would be worth turning on for the build-bot, as it does slow down the check considerably, but it will probably catch a few more errors.
