make_expression with ec broken in v0.172.0

[meierfra-ergon]

after update to 0.172.0 my code using following make_expression() function

template <class Json>
jsonpath_expression<Json> make_expression(const Json::string_view_type& expr,
    std::error_code& ec);

(https://github.com/danielaparker/jsoncons/blob/v0.172.0/doc/ref/jsonpath/make_expression.md)
does not compile anymore. it seems a wrapper function is missing in jsonpath_expression.hpp
something like:

template <class Json>
auto make_expression(const typename Json::string_view_type& expr, std::error_code& ec) {
  return make_expression<Json>(combine_allocators(), expr, custom_functions<Json>(), ec);
}

** What is the expected behavior?**
code should compile with make_expression(expr, ec)

What is the actual behavior?
compile error -> "no matching function for call to 'make_expression'"

Enumerate the steps to reproduce the bug

Include a small, self-contained example if possible

What compiler, architecture, and operating system?

• Compiler: clang14
• Architecture x86, x64
• Operating system: linux

What jsoncons library version?

• Latest release 0.172.0

BTW I think I found another bug, while writing the wrapper with make_expression(combine_allocators(), expr, ec) (using the 3 argument variant), it would not compile either.

Changing the inner call to make_expression()

jsoncons/include/jsoncons_ext/jsonpath/jsonpath_expression.hpp

Line 197 in c266fdf

return make_expression(alloc_set, expr, custom_functions<Json>(), ec);

to return make_expression<Json>(alloc_set, expr, custom_functions<Json>(), ec);
fixes this

Yes, thanks for reporting this, fixed on master.
