Starting Julia with --debug-info=2 provided enough information to locate the source of the problem. The debug output showed the offending line in TicraUtilities.jl. It was the start of the @compile_workload block. Bisection revealed the offending line, and I was finally able to trace the problem to the integrate method of the Dierckx.jl package, which is called by TicraUtilities. I’ll try to create a MWE and create an issue for it in the Dierckx repo.
Edit: Issue created here.
