            Bug ID: 63279
           Summary: Processes hang inside Linux Kernel built with gcc5
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: sasha.levin at oracle dot com

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 hangs indefinitely.

This issue was easy enough to bisect, and the offending commit is: 
https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=213753


Thanks,
