It seems that this problem is not new and existed in previous versions 
of MapServer. I have filed a ticket for it and the fix will be in the 
next beta:

   http://trac.osgeo.org/mapserver/ticket/2216

While we were at it, we have renamed --enable-covergae to --enable-gcov 
since the old name led users to think that the option might be related 
to enabling WCS or Arc/Info coverage which is not the case:

   http://trac.osgeo.org/mapserver/ticket/2217

It crashes with any of the Chameleon samples? It's possible that the 
sample mapfiles need upgrading, but that should not cause a seg fault. 
I'll have to try to reproduce that one.
