Asserting testcase

The attached code is reduced from an 'error on valid code' problem in
libs/asio/example/serialization/client.cpp. The reduced is 'assert on valid
code', backtrace:

t.cc:11:5: warning: control reaches end of non-void function [-Wreturn-type]
    }
    ^
Assertion failed: (DefinitionData && "queried property of class with no
definition"), function data, file
