This was from a build job we run, I will try to get these files and attach to this issue.

I think this is the same issue that I reported on Phabricator, which should be resolved with 58b9666, could you update to current main and see if it still reproduces?

[sudipm-mukherjee]

Thanks @nathanchance. Tried with latest HEAD and the crash is not seen with powerpc anymore. Sending the errors to lkml.
I guess this issue can be closed as its already fixed. Closing now.
