marisa is affected:

$ ag failure
lib/marisa/grimoire/io/reader.cc
139:    } catch (const std::ios_base::failure &) {
140:      MARISA_THROW(MARISA_IO_ERROR, "std::ios_base::failure");

lib/marisa/grimoire/io/writer.cc
140:    } catch (const std::ios_base::failure &) {
141:      MARISA_THROW(MARISA_IO_ERROR, "std::ios_base::failure");

and after rebuilding with g++-5

$ nm -D /usr/lib/x86_64-linux-gnu/libmarisa.so.0.0.0|c++filt |grep failure
                 U typeinfo for std::ios_base::failure[abi:cxx11]

so we need to rebuild it, perhaps also rename the package to
libmarisa0v5.
