[Lldb-commits] [lldb] [lldb][test] Free buffers in demangling tests to avoid leaks (PR #142676)

[Jordan Rupprecht via lldb-commits]

https://github.com/rupprecht created https://github.com/llvm/llvm-project/pull/142676

Test case added by f669b9c3eca9438d33259aefb8156f977f1df382 / #137793. Note that the `DemanglingParts` case above also frees the buffer; this new test case is inconsistent.
