Hi Erik, Thanks for all your great work. I found a set of bugs in resolv.c . Basically, there is code that looks like: BIGLOCK; __nameserversXX=__nameservers; __nameserverXX=__nameserver; BIGUNLOCK; i = __dns_lookup(dname, type, __nameserversXX, __nameserverXX, &packet, &a); which is a problem because the declarations are int __nameservers; char * __nameserver[MAX_SERVERS]; int __searchdomains; char * __searchdomain[MAX_SEARCH]; so you can see that __nameserver is a pointer. Copying the pointer to __nameserverXX doesn't protect the global variable space. I have attached a patch and the new file. I hope you will incorporate these bug fixes. I spent quite a bit of time tracking them down. Many thanks, Ron
