Hi,
<br>
<br>
When I ran the ViewExplodedGraph checker following the workbook
here:
<a class="moz-txt-link-freetext" href="https://github.com/haoNoQ/clang-analyzer-guide/releases/download/v0.1/clang-analyzer-guide-v0.1.pdf">https://github.com/haoNoQ/clang-analyzer-guide/releases/download/v0.1/clang-analyzer-guide-v0.1.pdf</a>
(BTW, this is the great workbook. I wished that I had seen it
earlier before tracing checkers in debug mode), I got an
assertion failure. The test code and command output are as
follows.
