            Bug ID: 38286
           Summary: ICE "couldn't find injected class name"
           Product: clang
           Version: trunk
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs
          Assignee: unassignedclangbugs at nondot.org
          Reporter: arthur.j.odwyer at gmail.com
                CC: llvm-bugs at lists.llvm.org

This is a regression; Compiler Explorer says it reproduces in trunk but not in
6.0.0.
