Well I direct the reply back to the list

Mmm do they get credit for post to the list & cc me hoping for a fix?
Mmm even if all the source/compilers/tools etc are freely available to  
fix it?
Mmm even with a nice gui front end to gnu debugger?
Mmmm then again I've suggested in the past that people should tell me  
if the mac vm crashes (shouldn't do that).

Lets see it does a EXC_BAD_ACCESS

The nasty line is this
	if (gDNSResolver->erf == NULL) //Sleep fix, other endpoints are more  
explicit about this issue.


(gdb) print gDNSResolver
$1 = (EPInfo *) 0x0

Oops

Lets see what's the stack
call printAllStacks()

Mmm well it is a bug, I don't check to see the global resolver has a  
valid value. That's fall out of assuming it gets initialized, but  
initialization of the network stuff isn't automatic because in days of  
dialup we didn't want the modem to dial if you loaded the network code.

I'll let Keith figure out what extra step he needs to do to avoid the  
problem.
