[racket] segmentation fault while compiling mzscheme 4.2.5 on Xen environment

FWIW, it built and ran fine for me recently under (IIRC) CentOS 5.3 x86 
32-bit under XenServer 5.5.

BTW, this is not an endorsement of Xen, and I recommend KVM over Xen for 
most techie purposes.  If you are able to switch to KVM, you might be 
able to do so with less effort than debugging this particular instance 
of Xen pain.
