            Bug ID: 32361
           Summary: `ninja check-asan` fails when using LLVM_ENABLE_LIBCXX
           Product: compiler-rt
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: compiler-rt
          Assignee: unassignedbugs at nondot.org
          Reporter: chandlerc at gmail.com
                CC: llvm-bugs at lists.llvm.org

The failure mode differs depending on if I have LLVM_ENABLE_LLD turned on or
off, but it fails either way for me:

With LLVM_ENABLE_LLD=OFF I get:
