There is a revised patch that has finally been tested after someone's vacation.
Deepthi, please share the link to the patch on this list once it's sent.

Andrew, Is Rogério's confirmation, that reverting r12-10250-g8ec265c1464dec
avoids the error, sufficient to revert the commit on 12.4 or do you want
someone to write a test case, confirm it works on 12.3's t

Alex, thanks for confirming, I was worried that it was one of the _perfectly_
sensible local patches we have in YP. ;-)
FYI, a local toolchain expert has started working on this defect so stay tuned

Any progress or need for additional information?
What should I expect over the coming weeks?

This ICE still happens with gcc-7.2.
Here's the stacktrace:

Here is the 'bt' and 'bt full' with line numbers and symbols. YP diff to enable
this is below as well. Thanks for you patience as I re-learn these ropes.

Yes, the host is an x86-64-linux system running Ubuntu-16.04.1.
The cross-compiler was built using the Open Embedded (OE) build system so of
course, it's not part of Ubuntu.
I did get a better backtrace as

With both patches applied:
1. The "minimal testcase produced by the delta utility" no longer ICEs the
toolchain.
2. The "smaller reproducer with manual work-around " DOES STILL result in an
ICE as does the

Is anyone working on this bug? I'm not pushing, but rather trying to understand
what to expect.

I agree that the creduce output should be ignored. :(
I ran 'delta' again with a manually cleaned up input and I got a minimal
reproducer that is shorter:

I also used the delta utility to produce a larger reproducer. I'll attach it as
jdcolor-altivec-testcase-min.i along with the full preprocessor output in case
it's useful to have additional context.
