the funny thing is that the source can be preprocessed successfully with "-E", and it compiles just fine.

#1 Updated by Kefu Chai 8 months ago

cannot reproduce this issue on GCC-8.

i am pointing the gcc/g++ on omani slaves to gcc-8 manually.

reproduces it.

please note, i cannot reproduce it by compiling it on the same machine with the same setting but with a different source dir like "/home/kchai/ceph"

#3 Updated by Patrick Donnelly 8 months ago

Kefu, on ceph-devel you said this was addressed. Did you mean that a ticket (i.e. this one) exists for the issue or that it's been fixed?

I'm still seeing this with a test build on top of today's master: https://jenkins.ceph.com/job/ceph-dev-new-build/ARCH=x86_64,AVAILABLE_ARCH=x86_64,AVAILABLE_DIST=centos7,DIST=centos7,MACHINE_SIZE=huge/16386//consoleFull

#4 Updated by Kefu Chai 8 months ago

Patrick, latter, but i was wrong. as i thought it happened on arm64 only. but it now shows up on both archs. =(

#5 Updated by Kefu Chai 8 months ago

now, master build on bionic is broken due to the ICE on GCC 7.3.
