 Currently, there are six situations, where exceptions happen automatically in Solidity:
 
-1. If you access an array beyond its length (i.e. ``x[i]`` where ``i >= x.length``).
-2. If a function called via a message call does not finish properly (i.e. it runs out of gas or throws an exception itself).
-3. If a non-existent function on a library is called or Ether is sent to a library.
-4. If you divide or modulo by zero (e.g. ``5 / 0`` or ``23 % 0``).
-5. If you perform an external function call targeting a contract that contains no code.
-6. If a contract-creation call using the ``new`` keyword fails.
+1. If you access an array on or beyond its length (i.e. ``x[i]`` where ``i >= x.length``) or below zero.
+2. If you access a fixed-length bytes on or beyond its length, or below zero.
+3. If a function called via a message call does not finish properly (i.e. it runs out of gas, has no matching function, or throws an exception itself), except when a low level operation ``call``, ``send``, ``delegatecall`` or ``callcode`` is used.
+4. If a non-existent function on a library is called or Ether is sent to a library.
+5. If you divide or modulo by zero (e.g. ``5 / 0`` or ``23 % 0``).
+6. If you perform an external function call targeting a contract that contains no code.
+7. If a contract-creation call using the ``new`` keyword does not finish properly.
+8. If a contract is called but there are no matching interface or fallback function.
 
 Internally, Solidity performs an "invalid jump" when an exception is thrown and thus causes the EVM to revert all changes made to the state. The reason for this is that there is no safe way to continue execution, because an expected effect did not occur. Because we want to retain the atomicity of transactions, the safest thing to do is to revert all changes and make the whole transaction (or at least call) without effect.
