Well, this pretty much smells like running in a VM that doesn't support
or allow AVX instructions (Jaguar /does/ support).

(Exactly the same tests failed with SIGILL recently in a Xen 4.1 VM
where AVX was disabled, or more precisely, not enabled [1] [2].)

P.S.:

If you try a *snapshot* as Marc suggested, you could try configuring with

  ./configure --prefix=$HOME/local --build=jaguarnoavx-linux-gnu

in order to suppress AVX instructions; unfortunately this does *not*
work with the /stable/ (6.0.0) release [3].
