The original code had ENDPOINT_MAX and HST_ENDPOINT_MAX switched.
Also the first loop was off by one, it started past the end of the array
and went down to 1 instead of going down to 0. The test at the end of
the loop to see if we exited via a break wasn't right because
"tmp_endpoint" is always non-null here.
