Any ideas how to fix it?

[moneroexamples]

New gcc seem not to allow switch cases to fall through.

A possible fix could be adding __attribute__((fallthrough)); to the switch statements that it happens. This happens in two files:

1. ~/solidity/libsolidity/codegen/CompilerUtils.cpp

In line 784 add: __attribute__((fallthrough));, so this should look like:

            // stack: <address> <function_id>
            m_context << Instruction::POP;
            break;
        }
        __attribute__((fallthrough)); // <- this is added
    }
    default:

2. ~/solidity/libsolidity/codegen/ExpressionCompiler.cpp

In line 1046 add: __attribute__((fallthrough));, so this should look like:

                // not found in contract, search in members inherited from address
                alsoSearchInteger = true;
        }
        if (!alsoSearchInteger)
            break;
        __attribute__((fallthrough)); // <- this is added
    }
    case Type::Category::Integer:

I will make issue on solidity shortly.

Hope this helps.
