Comment (by vossman):

 Alright, some interesting info. I compiled my own _nd_image.so from the
 scipy on my x86_64 Fedora 10 machine.

  * Packaged Scipy v0.6.0 (noarch=?): result = Illegal instruction
  * Compiled Scipy v0.6.0 (noarch=False): result = Illegal instruction
  * Compiled Scipy v0.6.0 (noarch=True): result = Illegal instruction
  * Compiled Scipy v0.7.0b1 (noarch=False): result = [2 3]
  * Compiled Scipy v0.7.0b1 (noarch=True): result = [2 3]

 '''So what has changed in ndimage between scipy v0.6 and v0.7?'''

 Also, grep flags /proc/cpuinfo:

 {{{
 flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge
 mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht
 tm pbe syscall lm constant_tsc arch_perfmon pebs bts rep_good
 nopl pni monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr dca lahf_lm
 }}}

 '''Machine Test Summary:'''
  * Fails on 1 machine with Fedora 9 on i686 Pentium 3 (scipy v0.6)
  * Fails on 4 machines with Fedora 10 x86_64 (scipy v0.6)
  * Fails on 1 machine with Open Suse 11.0 with x86_64
  * Fails on 1 machine with Open Suse 11.0 with i686
  * Works on 1 machine with Fedora 8 on i686 Pentium 4 (scipy v0.6)
  * Works on 6 machines with RHEL 5 x86_64 (AMD and intel, scipy v0.5.2)
  * Works on pv's machine with 32-bit Ubuntu (Scipy 0.6.0 & 0.7.0.dev5294)
  * Works on pv's machine with 64-bit Debian Etch (Scipy 0.7.0.dev5268)
