Which source file causes the icc internal error? It looks like icpc 9.0 segfaults when compiling CheapRNG.cc. (Unfortunately I don't have icc ia64 10.0 here...) 

The gcc problem is certainly fixable by using separate code on IA64.  Back in the day icc was much, much faster than gcc--I'd imagine that is still the case today. Let's try to figure out what code is causing problems with icc before switching to gcc.

I dont know if there is any hope for the icc compiler, but any thoughts on the gcc issue would be awesome.
