A doxygen comment like this will crash doxygen, with at least 1.7.1, 1.7.2 and the svn version. It didn't crash in previous versions.

valgrind shows that it happens here:

I didn't get this crash, not did valgrind show any issues, but I see that stripEmptyLines does not properly handle the case were s is a null pointer, so I'll fix this.

This bug was previously marked ASSIGNED, which means it should be fixed in
doxygen version 1.7.3. Please verify if this is indeed the case. Reopen the
bug if you think it is not fixed and please include any additional information
that you think can be relevant.
