Hello! What is that? In this error report there is no compile log, nor
any file / line. And "Link:" line from above error report does not work.
Intel, can you look at your robot? This looks some bug in error reporting.

Looks fine to me: this is not a compile problem, but an assembler problem.
Presumably this is when building a kernel for a PPC platform that does
not support the eieio instruction?
The Link: works fine for me, sometimes you just have to be a little bit
patient for the archiver to catch up...

What is fine on this report? There is completely missing command which
generated this error; whole error message; input files which caused them
and also change or commit.
And what presumably happened? I'm really not going to spend more time on
guessing what reporter could probably might wanted to write into the
report and start looking into crystal ball what could be an issue.
I can say that this issue presumably happened when email operator of
this robot pushed incorrect button and instead of the real report, it
sent test report with content of some random error line from the random
log file.
Are we on the technical discussion about exactness? Or are going to
discuss what who think that what could happened?

Sorry, I do not have time to wait undefined amount of time to access
additional resources which are based on reported details required for
debugging.
Intel, could you please react on this issue? If not, I'm going to add
your robot to my black list. It is not first time when I received such
useless report from you and nobody reacted on it.

The file name is indeed missing.

That is mentioned, and looks like a valid possible introducer.

It's randconfig, and the config is provided, incl. steps to reproduce.

The Link is just a reference to the email you received in your mailbox,
and to all follow-ups.

Well, you are the one who authored the offending commit, and at
first glance, it looks like a reasonable culprit that could introduce the
failure mentioned ;-)
Presumably you forgot to cater for a very specific combination of
config option values?
