You are probably right. It may be an issue in C library/OS. I will try 
and discuss this in freeBSD lists.

Now here is something that spoiled my sleep: I wrote a small test 
program to call getgrgid(), and it prints getgrgid()->gr_name = www. 
When I added a print statement inside common.c, I get 
getgrgid()->gr_name = null (it goes to http error log, since http 
headers are not defined at this stage of the code).

Anyways, thanks again for your help..
