            Bug ID: 38566
           Summary: Backend error compiling on c5.2xlarge
           Product: clang
           Version: 3.8
          Hardware: Other
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: danil at vast.com

When I try to build my library using llvm-3.8 on an EC2 instance with
instance_type t2.2xlarge, my code compiles normally without issue.

The same machine image (ami), with the same build scripts, launched with
instance type c5.2xlarge, suffers the fatal error shown below.
