--- Comment #7 from Sasha Levin <sasha.levin at oracle dot com> --- The built was from a clean checkout. auto-host.h seems to be correctly created during the build. I see this after the build failure: $ stat host-x86_64-unknown-linux-gnu/gcc/auto-host.h File: `host-x86_64-unknown-linux-gnu/gcc/auto-host.h' Size: 47262 Blocks: 96 IO Block: 4096 regular file Device: fe00h/65024d Inode: 15209562 Links: 1 Access: (0644/-rw-r--r--) Uid: (10017/ sasha) Gid: (10017/ sasha) Access: 2014-10-29 15:59:10.713463956 -0400 Modify: 2014-10-29 15:59:09.677398847 -0400 Change: 2014-10-29 15:59:09.685399348 -0400 Birth: -
