To tentatively address a non-reproducible segfault associated with `clang` compiler, the build was just restarted after installing an updated version.

| | Before | After |
| --- | --- | --- |
| Clang version | 10.0 | ~~14.0.0~~ 14.0.6 |

### Details

_Text below copied from pull-request [Slicer/DashboardScripts#/57](https://github.com/Slicer/DashboardScripts/pull/57) description_

This updates was motivated after observing a clang `EXC_BAD_ACCESS` error that is not consistently reproducible.

Here are some of the observed occurrences of `Error while building C++ object file`:

1. `CMakeFiles/PythonQt.dir/generated_cpp_511/com_trolltech_qt_gui/com_trolltech_qt_gui0.cpp.o`
2. `CMakeFiles/dcmect_tests.dir/t_roundtrip.cc.o`
3. `Code/BasicFilters/src/CMakeFiles/SimpleITK_ITKBinaryMathematicalMorphology.dir/sitkBinaryDilateImageFilter.cxx.o`
4. `Code/BasicFilters/src/CMakeFiles/SimpleITK_ITKCommon.dir/sitkCastImageFilter-2v.cxx.o`
5. `Code/BasicFilters/src/CMakeFiles/SimpleITK_ITKConnectedComponents.dir/sitkConnectedComponentImageFilter.cxx.o`
6. `Code/BasicFilters/src/CMakeFiles/SimpleITK_ITKConvolution.dir/sitkFFTNormalizedCorrelationImageFilter.cxx.o`

These errors did not all happen in the same build. In the case listed above:

- (1) and (2) were two different clean build
- (3), (4), (5) and (6) were reported in the same build

### Segfault

In all cases, the message reported was similar to the copied below and attempt to re-run the associated sh script (e.g `com_trolltech_qt_gui0-17dcc3.sh`) did not lead to a segfault.
