Yes: That was a MacBookPro3,1 with a 2.2-GHz Core 2 Duo and Mac OS X  
10.4.11.

That should not be the case. I'm under the impression you have to use  
"-arch x86_64" in the LDFLAGS/CFLAGS to get 64-bit Intel code generated.

I also tried on a MacBookPro2,2 with a 2.16-GHz Core 2 Duo and Mac OS  
X 10.5.3. All tests passed. I rebooted that machine into Mac OS X  
10.4.11 and tried again, and all tests still passed.

I also tried on a PowerMac3,4 with a 466-MHz PowerPC G4 and Mac OS X  
10.4.11, and all tests passed.

I rebooted the 2.2-GHz problem Mac to Mac OS X 10.5.3 and all tests  
passed there too. So apparently I have a problem with my 10.4.11  
installation on my 2.2-GHz Mac. I think I'll go away now and see if I  
can solve that.

I would love to know how the arithmetic test (or maybe q in general)  
does its math though. I can't get any other app to tell me that 2 * 2  
== 4.4501477170164897e-308, and finding out how it's computing that  
might help me isolate what's wrong with my computer.
