dbgutil build failure in libreoffice-4-1 and master: copy-construct of singular iterator

Hi,

For several days straight now, I've been unable to build master or
libreoffice-4-1, because several unittests fail with something like
the below.

Anybody else getting that / any clue what is going on?

$ gcc --version
gcc (Debian 4.7.2-5) 4.7.2
$ dpkg -l libstdc++6-4.7-dev
ii  libstdc++6-4.7-dev        4.7.2-5           amd64             GNU Standard C++ Library v3

$ dpkg -l libmdds-dev
