Recently several posts asking for debugging help were cross-posted from Stack Overflow to Code Review after people suggested CR in their comments. Debugging is off-topic on Code Review. From our FAQ:
and your question is not about … Trouble-shooting, debugging, or understanding code snippets [emphasis added]
Please do not encourage cross-posts, especially off-topic ones. If you feel that a question belongs on Code Review, flag it for moderator attention and they will migrate it if necessary. Cross-posting and bouncing questions around the network will only raise tempers and keep questions from being answered.
