            Bug ID: 46953
           Summary: Modules crash with pure virtual base method
           Product: clang
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Modules
          Assignee: unassignedclangbugs at nondot.org

Repro test case: https://reviews.llvm.org/D85084, output:
https://reviews.llvm.org/P8228.

I tried to reduce the test case as much as possible, but the setup is still a
bit complicated.  The crash itself appears in
`clang::CXXRecordDecl::markedVirtualFunctionPure()`.
