The same problem occurs on code looking like the following:

template <bool a, bool b>
struct Templ<a || b> {};

Here the generated LaTeX looks like

\hypertarget{structTempl_3_01a_7_7b_01_4}{
\section{Templ\texorpdfstring{$<$}{<} a$|$$|$b \texorpdfstring{$>$}{>}
Struct Template Reference}
[...]

where there are two occurrences of $|$.
These too should be replaced by something like

    \texorpdfstring{$|$}{|}

but it is unclear to me where such a correction should be applied.
