In case you remember: why did vsnprintf() fail in that example?  If I
understand what C99 says correctly (a big if), then

 printf("%s\n", some_nonsense_string);

should always just work.

ltrace indicates that something is wacky about the format string.

 vsnprintf("Author: ", 143, "%s: %.*s%.*s\n", 0xbf8b5738) = -1

The regexes in http-backend are lc_collate- (but probably not lc_ctype-)
sensitive.  I am not sure how to go about exhaustively tracking down
ctype-dependencies.
