getgrouplist segfault?

[Anton Monroe <akm meer net>]

I'm no developer, but this seemed like the best list for this.  

Once in a while I try out an MC snapshot from ibiblio.org.  A few months
ago I noticed that something had changed that broke MC on my computer,
but I didn't have time to look into it until yesterday.

I've never used CVS before, but I think I did it right.  I downloaded
and compiled versions of MC as of various dates, and narrowed down my
problem to something that changed on January 30, 2005.  

The symptom is that when I try to start MC as root, it immediately gives
a  segmentation fault.  When I start it as a normal user, it works.  The
only  thing I can see that changed on January 30 is something called
'getgrouplist'. I don't know what that is.  Below is a complete diff
between the version that works for me and the one that doesn't.  This is
on a Linux machine; originally SuSE 7.3 but with updated versions of a
lot of things.

Any ideas?  Any more information I should give you?

Anton
