We saw the following stack overflow in our tests, using JET v0.8.21 using Julia 1.10.2 using

analyze_from_definitions=true,
concretization_patterns = [:(x_)],
target_defined_modules=false,
mode=:typo
  StackOverflowError:

Perhaps there is a cycle causing the stack overflow? Any idea how to mitigate this?

Actual tests running the analyzed code did not run into stack overflow.

Thanks!
