This is Canonical's bug tracker and you seem to be reporting a defect with their build of gcc. If that is the case, you should be talking with Canonical. The gcc bug tracker is https://gcc.gnu.org/bugzilla/. The diff you provide there seems to be detecting when you've looped 2^32 times, because somethings scrogging the object list to become circular. That's the actual defect that needs fixing. nathan -- Nathan Sidwell
