            Bug ID: 30928
           Summary: check-lldb-unit fails on r286085,
                    TestArm64InstEmulation.TestSimpleDarwinFunction failed
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs

    Classification: Unclassified

check-lldb-unit fails on Linux x86_64 (building with gcc 6.2.1).

Here is my directory structure:

llvm/
llvm/projects/libcxx
llvm/projects/libcxxabi
llvm/tools/clang
llvm/tools/lldb

Here is my entire cmake configure line:

~/llvm/trunk-ccll/llvm/R (127) $ cmake -G Ninja -DLLVM_TARGETS_TO_BUILD=X86
-DLLVM_ENABLE_ASSERTIONS=Off -DCMAKE_BUILD_TYPE=Release
-DLLVM_INCLUDE_EXAMPLES=Off -DLLDB_DISABLE_LIBEDIT=On ../

Here is the test failure. Note, after this failure, the unit test driver hangs
forever in GDBRemoteClientBaseTest.InterruptNoResponse. I can file a separate
bug for that if needed.
