In C++, a multi-line macro redefining a class causes a "Runaway argument" problem in a hyperlink in LaTeX.

With the minimal example given at the bottom of this report, the generated LaTeX documentation causes pdflatex to crash with:

Runaway argument?
{\}^^M\hyperlink {classA}{    A}();\(\backslash \)^^M  \};    \(\backslash \ETC
.
! File ended while scanning use of \hyperlink.

This is due to \hyperlink{classA}{\} being in the generated .tex file.

The example originally had A as a templated class, with the macro defining a specialisation, so although the example code isn't valid C++, the additions that would cause it to be valid do not make the Doxygen error go away.

Reducing the first definition of A to a forward declaration causes the error to go away, as does putting the macro all onto one line, or removing the constructor.

This did not result in an error in release version 1.8.0, but does in the latest SVN version: 1.8.0-20120429 (rev. 813).

Doxyfile:
EXTRACT_ALL = YES

class A

    A();\
