Hi,
First, you did not provide the test case which is failing for
you. Second, are you sure you're passing "fs::native" as
second parameter to 'path' ctor?

A test-case would be:
#include <boost/filesystem/operations.hpp>
int main() { boost::filesystem::path path(":"); }
(which dies on unhandled exception, ie. SIGABRT, on Debian)
However, your point about missing second argument of
boost::filesystem:native is correct, and removes the
exception ;).
This brings me to read the specification, which correctly
defines the range of allowed characters, but, I must wonder
why would not all legal filenames be accepted by default.
Also, why would this default-path-format not be listed in
the enumeration path_format.

I think that there's no need to list this style in enumeration,
since you have single-parameter ctor. As for generic grammar
rationale, Beman (the library author), might know better, but
I think it's a good thing. Say, if you create a name with "*"
and pass it to system, you can be surprised. The current
semantic prevents you from unintentionally using unportable
syntax.
In case you'd like to continue this discussion, I think mailing
list would be better.

Poster was apparently not specifying native ctor argument.
Note that the complaint about being excessively nannyish
will be resolved in 1.34.0
