I strongly concur with Jeff's suggestion of using ldd mapserv. 
Segmentation fault after the end of a plain & simple "mapserv -v" really 
smells a binary that links to 2 versions of the same lib, and clashes 
during deallocation of static variables (although I would expect it to 
also crash in all situations, but behaviour might be quite unprectible). 
And the usual suspects are indeed the ones listed by Jeff.
