Not reproducible for me (and do you really think that something as simple as this would not have been found on x86_64 long before now?)
This is almost certainly caused by your use of an inappropriate external BLAS. Something has probably been compiled for a different processor than the one you are using, since illegal instructions are a compiler (not R) issue that I have seen quite often on ix86 systems when this happened. Use --without-blas when recompiling R and see if it then works.
