<pre>We have found a weakness using PVS-Studio tool. PVS-Studio is a static code
analyzer for C, C++ and C#: <a href="https://www.viva64.com/en/pvs-studio/">https://www.viva64.com/en/pvs-studio/</a>
Analyzer warning: V595 The 'Initializer' pointer was utilized before it was
verified against nullptr. Check lines: 335, 338. semaoverload.cpp 335
