Marking this as wontfix on that basis.

However, I notice that the removal bug is marked moreinfo, because the
ftp-masters will not remove insighttoolkit 3 while packages still depend
on it, unless those packages are also removed. Please tell that bug how
you plan to deal with this.

Does insighttoolkit4 still have a C++ ABI involving std::string,
std::list or other affected symbols? If it does, it will need a similar bug.

The transition can be done either by moving from one SONAME to another
(libinsighttoolkit4.7 -> libinsighttoolkit4.8), or by adding a v5 suffix
to 4.7. The people who have already spent a month fighting with this
transition would really prefer the short-term answer to be "whichever is
quicker and lower-risk", which seems likely to be the v5 suffix; you can
still do the 4.7 -> 4.8 transition later, after unstable is a usable
suite for development again.

Leaving insighttoolkit4 built with g++-4 is not a valid solution,
because it already needs to be rebuilt with g++-5 for the dcmtk2v5
sub-transition (although it FTBFS right now - I'll open a bug).
