Hi Nicholas,

The admin of the buildbot is aware of this, will handle it after long
weekend. Thanks.

      According to buildbot log here
      http://lab.llvm.org:8011/builders/clang-ppc64be-linux/builds/37730/steps/cmake%20stage%201/logs/stdio

       for Simon's example ICE.

Greetings,


That version of gcc seems to be outdated now. For that major version its


on 7.4 now so you may want to try that to see if its already been fixed


as a regression. If not thats considered a serious regression and should


be reported. If Finkel can also send me a log of the build utput I can


probably tell him how to get a trace but its a little hard to tell without


that.


Regards,


Nick

      The log says "c++: internal compiler error: Killed (program cc1plus)"
      -
      so that looks like a GCC ICE. Do we know what version of GCC that bot
      is
      running?

        is

            an example of the ICE when D64146/rL370584 landed.

                        Hello PowerPC fans,

                        I am attempting to land D64146 and the PowerPC bots
                        crash with an
                        internal compiler error. Can anyone help me to
                        reproduce the crash
                        or obtain a stack trace somehow?


                  I think a link to the failing build would be helpful.

                  Cheers
