Interesting, please do the following:

Use 'make ENABLE_OPTIMIZED=1 VERBOSE=1'

To get the llvm-gcc invocation that is failing.  Once you have that, 
something like the following should reproduce it:

1. Replace -c -o foo.o  with "-c foo.bc -emit-llvm"
2. Run "llc foo.bc"

If that crashes, please run "bugpoint -run-llc foo.bc" and attach the 
output to a bugzilla (llvm.org/bugs/).  If llc doesn't crash, please 
attach the .ii file to a bugzilla.

Thanks Mike!
