C++ function with default function arguments not parsed correctly

[Ulf Lorenz]

Hi,

I have a C++ project with a function

RTensor readStructuredData(std::istream& input, std::string separators = " \t");

When I generate the doxygen output, I get warnings that the documented parameter "separators" does not exist. Also, the whole doxygen output only uses the function with the first argument and completely discards the "separators" argument.

I tried to create a minimal working example, but when I do so, everything works fine. Therefore, I can only link to my project (https://sourceforge.net/p/wavepacket/cpp), where the latest release and the git master both have this problem. The function in question is under include/util/file_utils.hpp. The doxygen version I used was Debian stable (1.8.13).

After standard cmake setup, the target "build-doc" builds the documentation.
