I have been unable to find it so far.
How do I detect a cyclic dependency?

If I get all the .so loaded, extract the DT_NEEDED for each and check if there is a loop, would that
be enough?

It is possible that some .so calls dlopen() in the init phase. Would that be relevant in this context?

I have tried, but I cannot reproduce it at all in a simplified context.
