I have a program running in the Juno Julia console, which under unclear circumstances seems to diverge. The Juno command `Interrupt Julia` doesn’t seem to work. Any hints how to debug in this scenario? Thank you.

NB: this is pure Julia code without external dependencies, so there are no foreign language libraries involved on my side. And the program does no math stuff involving BLAS, LAPACK etc.

NB: also no `@inbounds`

NB: I’m using `_growend()` on vectors

Try to use `Infiltrator.jl`. Excellent tool for this sort of problem.
