Application developers have a tendency to use krb5_get_error_message() as a drop in replacement for error_message() and under various circumstances they pass in a NULL context. This method works fine for MIT's implementation which ignores the context but in Heimdal passing in a NULL context would dump core. This patch set modifies krb5_get_error_message() in order to permit the passing of a NULL context. First, if the context is NULL, an attempt will be made to allocate one locally for the purpose of evaluating the error code. Second, if a local context cannot be allocated, fall back on calling error_message(). If error_message() fails to return a string, then generate an "unknown error" response. Only if all of the above fails is NULL returned. Change-Id: If4baf7d6c428cf0baf11c044b8dfd5c2b3cdf7e4
