Describe the bug
I ran ApplicationInspector against the dependabot-core repo, and it crashed with a stackoverflow exception.

To Reproduce
Steps to reproduce the behavior:

  1. git clone https://github.com/dependabot/dependabot-core
  2. appinspector analyze -s dependabot-core -N

Expected behavior
Application inspector runs and outputs the analysis

Operating Environment (please complete the following information):

  • Application Inspector Version: ApplicationInspector.CLI 1.9.22+911e9d3be0
  • OS: Ubuntu (GitHub Codespaces environment)

Additional context
Here's a snippet of the log before the crash (there are 40k instances of this first line before it dies)

Interestingly, this one doesn't reproduce if you enable verbose logging.

Sorry, that doesn't seem to be true. It didn't reproduce with this command:
appinspector analyze -v verbose -s dependabot-core -l ./log.txt

but it did with this one:
appinspector analyze -v verbose -s dependabot-core -l ./log.txt -f sarif

Thanks for your report and the follow up info. That might indicate its somehow specifically in the sarif export path. I'll investigate this week.
