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.

Thank you! If no renaming is needed, then you only need to bump the package
version, rebuild and upload.

Actually, after rebuilding with 5.2, there's only one symbol with cxx11 ABI
substring:
   U typeinfo for std::ios_base::failure[abi:cxx11]

Cheers,
