[Libva] vainfo crashes with "Program received signal SIGFPE, Arithmetic exception." Need help to troubleshoot.

Hi,

I'm building libva-git on 2 boxes, both Linux x86_64.

They're *supposed* to be identically configured.

I build it the same on both boxes:

	git clone git://anongit.freedesktop.org/git/libva
	cd libva
	./autogen.sh
	./configure --libdir=/usr/local/lib64 --enable-dummy-driver
	--enable-glx --enable-egl
	--with-drivers-path=/usr/local/lib64/dri
	make
	make install

Afaict there's no build errors, and I end up with

@ box #1

	ldd /usr/local/lib64/libva.so
		linux-vdso.so.1 (0x00007fff7278b000)
		libdl.so.2 => /lib64/libdl.so.2 (0x00007f53b7745000)
		libc.so.6 => /lib64/libc.so.6 (0x00007f53b73a0000)
		/lib64/ld-linux-x86-64.so.2 (0x00007f53b7b9a000)

@ box #2

	ldd /usr/local/lib64/libva.so
		linux-vdso.so.1 (0x00007fff627ff000)
		libdl.so.2 => /lib64/libdl.so.2 (0x00007f29fe7d9000)
		libc.so.6 => /lib64/libc.so.6 (0x00007f29fe434000)
		/lib64/ld-linux-x86-64.so.2 (0x00007f29fec35000)

But when I run `vainfo` on both boxes, one works the other fails

So gdb shares where the problem is, but I'm not sure what to DO about it
:-/

I guess it's got to be something unique to one machine.

I'd appreciate any guidance on how to troubleshoot this one! 

Cheers!
