vim-enhanced oddness

[Ken Snider]

Using x86_64 test1 release.

when using vim (/usr/bin/vim), and creating a file:

[root at dw1.dw root]# vim blah

..typing some text, then saving with :wq, presents the following:

Vim: Caught deadly signal ILL
Vim: preserving files...

Vim: Finished.
Illegal instruction

../bin/vi does *not* have this problem,

Any ideas? any output I can capture to help narrow down the issue?
