Thanks for the report!
To reproduce it, I did this:

    $ LC_ALL=fr_FR.utf8 ./printf %1.2500000000s x
    zsh: bus error  LC_CTYPE=fr_FR.utf8 ./printf %1.2500000000s x
    [Exit 135 (BUS)]

Actually that's due to a bug in glibc that affects even the very
latest in CVS.  I've dug a little and reported it upstream:
