<p>Hmmm, it seems that a C++17-ism has crept into Scintilla LTS version.</p>
<p>My interpretation is that the default implementation of <code>Scintilla::UniqueStringSet::UniqueStringSet()</code> is not <code>noexcept</code> because although C++11 defined <code>noexcept</code> it was not until C++17 that the <code>std::vector</code> default constructor was made <code>noexcept</code> so the default constructor for <code>Scintilla::UniqueStringSet::UniqueStringSet</code> cannot be <code>noexcept</code> and so it conflicts with the explicitly specified <code>noexcept</code>.</p>
