Follow-up Comment #1, bug #52763 (project lwip):

Can we simplify the cleanup code in the build domain functions?
Maybe having just a goto in the LWIP_ERROR macro and freeing the domain and
return in a common block?

Running realloc on each adding of a name to a domain seems like it will
fragment memory very quickly - or maybe many of the realloc calls will need to
do nothing if more memory than requested is given earlier.

I have not used lwIP with locking so I have no comments there.
