build failures after stdlib update

Hello Current, 

	I am wondering if someone could help me please. 

	I built the 9.0-current kernel and world while there was still a bug in 
the updated strlen(). Unfortunately this rendered the machine unbootable as 
gptzfsloader crashed and would just echo an endless stream of spaces across 
the screen. After booting off another drive and reverting the gptzfsboot to 
the .old version, I was able to being the machine back to life, but 
applications were dieing left and right (Signal 10). I used dgb to find the 
offending library /lib/libc.so.7 and had a copy of the library from 3 days 
ago. After reverting that library, I was able to start all my applications OK 
and the machine is working.. 

	However..... 

	I am not able to build the latest world (I havent tried kernel yet). 
Whenever I start  gengtype dies with a signal 10.  I have tried to use dgb to 
examine the core file, but it gives me nonsense answers so I am not able to 
locate what library it might be trying to use. I have also tried to blow away 
the /usr/src and /usr/obj directories and recreate them from svn just incase 
there was something hanging on from the previous build. 

	Can anyone give me advice on how to track this problem down or fix it? I 
suspect I still have a lib that still trying to use the broken libc.so.7 or 
something else depended on it, but I am not sure.. 

Thanks, 
Peg
