The problem seems to be an old one,
http://www.runcode.us/q/c-debug-builds-broke-in-snow-leopard-x-code

Looking at the interesting parts of ostream.tcc, I saw a mysterious comment

      // _GLIBCXX_RESOLVE_LIB_DEFECTS
      // 117. basic_ostream uses nonexistent num_put member functions.

and googling a bit I found
http://gcc.gnu.org/onlinedocs/libstdc++/ext/lwg-defects.html#117

hmm... no idea how to fix this yet, but apparently this is a bug in
the oldish version of GNU libstdc++ that Apple ships?
