The recent change of the TRACE session interface triggered the
following warning:
/home/no/src/genode/repos/base/include/base/ipc.h:79:4: warning: ‘ret’ may be used uninitialized in this function [-Wmaybe-uninitialized]
*reinterpret_cast<T *>(&_sndbuf[_write_offset]) = value;
^
In file included from /home/no/src/genode/repos/base/src/core/include/trace/session_component.h:19:0,
from /home/no/src/genode/repos/base/src/core/trace_session_component.cc:15:
/home/no/src/genode/repos/base/include/base/rpc_server.h:132:42: note: ‘ret’ was declared here
typename This_rpc_function::Ret_type ret;
The warning occurs for basic return types (like size_t), which are
indeed not initialized. The variable gets its value assigned by the
corresponding 'call_member' overload, to which the variable is passed as
reference. But the compiler apparently is not able to detect this assignment.
Declaring 'ret' with a C++11-style default initializer fixes the warning.
