Given the following C++ code

class Foo {
  private:
    union { int x; char y; } v;
  public:
    int get_int() { return v.x; }
};

and a standard configuration file, except for EXTRACT_PRIVATE=YES, doxygen is generating incorrect LaTeX code for the private attributes of Foo. More precisely, the relevant fragment of the tex document is following:

\hypertarget{unionFoo_1_1@0_a16eddb7296c37d91335845d7b847c6b3}{\>int {\bfseries x}\\
\hypertarget{unionFoo_1_1@0_ae4b5d1d732df4608dbc4871c55b7f4b2}{\>char {\bfseries y}\\

where the second argument of \hypertarget is lacking a closing brace }.

Setting EXTRACT_ALL=YES in addition to EXTRACT_PRIVATE=YES results in a correct output.
