+``error: "Uncaught JavaScript exception: RangeError: Maximum call stack size exceeded.
+The compiler might be in a non-sane state, please be careful and do not use further compilation data to deploy to mainnet.
+It is heavily recommended to use another browser not affected by this issue (Firefox is known to not be affected)."``

+**A: Old versions of solidity compiler had this problem with chrome.**
+Please change the compiler version in Solidity Plugin to the newer one or use another browser.
