Additional info:
Comment 1 Marek Polacek 2016-02-17 09:19:01 UTC 
I can't reproduce this -- on which arch does this happen?
Comment 2 Jakub Jelinek 2016-02-17 09:42:29 UTC 
The dump is from x86_64.  But, I can't reproduce this either, with the same snapshot or even with the cc1 binary from the -0.10.fc24 rpm.
Comment 3 Oliver Kurth 2016-02-18 02:27:03 UTC 
Interesting. I did this in a docker container - I thought it wouldn't matter. I cannot reproduce this in a vm either. It's a slightly different version though:
gcc version 6.0.0 20160212 (Red Hat 6.0.0-0.11) (GCC)
Comment 4 Jan Kurik 2016-02-24 15:23:10 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle.
Changing version to '24'.

More information and reason for this action is here:

Comment 5 Marek Polacek 2016-03-10 15:15:35 UTC 
Is this still a problem with latest GCC build?
Comment 6 Oliver Kurth 2016-03-10 18:25:48 UTC 
It looks like the issue is gone. The build with
gcc version 6.0.0 20160305
does not throw any segfault any more (I am getting other errors, but those are not related). It's in a container updated to the latest rawhide, everything else is the same as in my original report.
Comment 7 Marek Polacek 2016-03-10 18:39:50 UTC 
Great, thanks.  I think we can close this one now then.
