Calling Julia Base.error() from C++

[canaknesil]

I am trying to call Julia Base.error method from C++. The example in README.md works fine:

julia> cxx"""
       void foo() {
         $:(println("Message.")::Nothing);
       }
       """
true

julia> @cxx foo()
Message.

But, when I replace println with error, I get this error:

julia> cxx"""
       void julia_error() {
           $:(error("This is the error.")::Nothing);
       }
       """
ERROR: Inferred Union or abstract type Union{} for return value of lambda

Not sure why but directly ccall "jl_error" works:

julia> cxx"""
              void my_julia_error() {
                  $:(ccall("jl_error", Cvoid, (Cstring,), "This is the error."));
              }
              """
true

julia> @cxx my_julia_error()
ERROR: This is the error.

This worked for me. Thank you.
