  • Thread-topic: Issues Related to GCC Compiler

We have seen domain save/restore/migration issues related to GCC compiler on recent changesets.
1. xen-unstable tree (changset 15080)
* gcc 4.0.2
Compiled with gcc 4.0.2, Xen rebooted AMD-V boxes during domain restore/migrate.
* gcc 4.1.2
This version of GCC worked well with Xen. It did not cause any problem so far.
2. xen-unstable staging tree (changeset 15172)
* gcc 4.0.2
Xen also failed (similar as changset 15080) on domain restore/migrate using gcc 4.0.2
* gcc 4.1.2
worked well.
We have not pinned the changeset which is causing the problem. I believe it should be one of the past 60+ changsets because changset 15017 worked well with gcc 4.0.2.
