            Bug ID: 42677
           Summary: Fix sharing of threadprivate variables with TLS
                    support.
           Product: OpenMP
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: release blocker
          Priority: P
         Component: Clang Compiler Support
          Assignee: unassignedclangbugs at nondot.org
          Reporter: a.bataev at hotmail.com
                CC: llvm-bugs at lists.llvm.org

If the threadprivate variable is used in the copyin clause on inner
parallel directive with TLS support, we capture this variable in all
outer OpenMP scopes. It leads to the fact that in all scopes we're
working with the original variable, not the threadprivate copies.

Bug fixed in r366483.
