according to http://www.boost.org/doc/libs/1_47_0/libs/filesystem/v3/doc/reference.html#Error-reporting (search for "exists"):
bool exists(const path& p);
bool exists(const path& p, system::error_code& ec);
Returns: exists(status(p)) or exists(status(p, ec)), respectively.

Throws: filesystem_error; overload with error_code& throws nothing.

I guess this hinges on what you think of as an error then, and you could argue that a file not existing *isn't* an error, it's just a condition.
