hi,
I have opened this bug https://bugs.launchpad.net/gcc-arm-embedded/+bug/1694644 as per the findings I had.
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.
