'fprint' does not do format string processing (unlike fprintf).
Therefore if some malicious translation is present in a .mo file, the
program will output it, but it will not crash from it. (Although if
it contains ANSI control codes, it may make your terminal go into
strange states or crash. But that's a bug in the terminal emulator.)

The security risks for setuid programs are handled through glibc/intl/
or libintl (on non-glibc systems).
