Lost in the bureaucracy

I have a question about usage of libraries, harming performance of other code. I thought the question would fit Code Review being a general point about coding, prepared and put it into CR.SE.

I invested some time to strip down to a short and understandable reproducible case, even prepared 'fire and forget' compile scripts, and - tried to - explain my worries in a concise and understandable way.

Posted it as Are libraries allowed to slow down normal function calls?.

I was asked to explain what the code does, which I did, yet didn't change the title (as requested); the question was ultimately downvoted and migrated to Stack Overflow. There it was again criticized regarding 'what it does', I explained and adapted the title. chux asked for unused variables and the output, want(ed) to provide that, the migration was rejected by Stack Overflow and is back on Code Review.

I tried to edit the original post on CR.SE, re-checked every advice in the help section and FAQ... and hoped that qualified, however find the path here confusing and irritating...
