Hi.
I've got weird issue with one of the OBS jobs which I don't know how to debug. From
time to time the build job fails.
It fails with "Illegal instruction" error - the code uses tricky SSE optimizations
which are heavily dependent on processor features.
The problem is that I do not see any pattern:
- any of the ubuntu or debian builds might fail (several or single)
- I'm unable to reproduce this locally
- the build failure is gone next day without any code changes
Overall this seems like some sort of spooky race condition. If I "trigger rebuild"
than the build is back to normal. I guess that it depends on what kind VM/CPU the
build has been scheduled on. Is there a way to get additional info about the VM on
which the build is running?
Example build log is attached but I'm unable to make sense out of it.
