[Lldb-commits] [PATCH] D72086: [lldb] Fix that SBThread.GetStopDescription is returning strings with uninitialized memory at the end.

[Raphael Isemann via Phabricator via lldb-commits]

teemperor added a comment.

For reasons that are beyond my understanding this change seems to break `SBProcess.GetSTDOUT` in random tests like this:

  ======================================================================
  ERROR: test_change_value_dwarf (TestChangeValueAPI.ChangeValueAPITestCase)
     Exercise the SBValue::SetValueFromCString API.
  ----------------------------------------------------------------------

  SystemError: <built-in function SBProcess_GetSTDOUT> returned NULL without setting an error
  Config=x86_64-/home/teemperor/work/ci/build/bin/clang-10

Anyone got a clue what is going on here? It seems like these tests only fail when run in combination with some other tests as running them alone is fine.
