That's correct. I'm just building in-tree and using 'git clean -df' to reset
everything back to a pristine checkout state when I need to.

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:

Thanks. I'll keep an eye on both of them, and will report here if the fix for
either of those fixes the segmentation faults I'm seeing.
Did you happen to bisect it down to the same commit?

But that... worked previously? Is backward compatibility intended to be broken
in this case?

Hi all,
I've observed segmentation faults on simple programs, such as:

PR61848 is talking about a "linux kernel boot failure when compiled using
trunk gcc.". In this case, the kernel boots just fine, but it has problem
executing tasks.
I've double checked that for:
svn+ssh://gcc.

After building and booting a Linux Kernel built with gcc5, several processes
would hang and consume 100% CPU, while other work just fine.
For example, /bin/dash would work great but /bin/bash just
