Bug.  Your solution is likely faster than the original, but both should work.

Judging by the error message, you found a very neat case where the
enable_if is both true and false, thanks to the implicit conversion
from char const[4] to char const*, so SFINAE can't prevent either
instantiation, leading to the ambiguity.
