Thank you for your investigation. I confirmed not rename package or soname.

1. marisa only use std::ios_base::failure in reader.cc/writer.cc
2. This just catch the exception, and throw an original exception (by
MARISA_THROW).
3. This original exception (Exception class) inherit std::exception
(not std::system_error).
4. marisa::Exception receive "std:ios_base::failure" as an error string.
5. Software link libmarisa will catch marisa::Exception only.

It seems that software which link libmarisa does not affect gcc5 transition.
I will upload package bumped up version to mentors,
and will send request for sponsorship.
