Hi,
When I ran the ViewExplodedGraph checker following the workbook here:
https://github.com/haoNoQ/clang-analyzer-guide/releases/download/v0.1/clang-analyzer-guide-v0.1.pdf
(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.
