No, I don't think it does.  The old (broken) ttyname() code would always
return the address of the internal static buffer.  The new code returns
NULL on error, as is required by SUSv3.

Since the old code returned a value, the tinylogin login app checks that
the value is correct.  When it finds that it isn't, it logs the error
message you report.  The string "/dev/misc" is simply what happens to
be in the ttyname static buffer at the time.
