Languages don't create bug, people create bugs and there will always be bugs. Instead of looking for the new hotness just study your chosen language more, carefully research your problem, spend more time designing your system to be fault more tolerant and test the system to find the bugs you do have. If we're talking only about languages introducing bugs it's best to have a mature language that works best for your problem and that you are proficient at.
