Thanks for the suggestion. It does smack of a hardware issue, doesn't  
it? But no, nothing else crashes; only when I compile some things  
with MacPorts. And I ran RAM, processor and logic board tests  
overnight and everything comes up clean.

I had this same problem maybe 6 months ago and found no hardware  
issue then either. I think I ended up uninstalling all of MacPorts  
and reinstalling the ports I used.

Today I was able to narrow the problem down to having gsed @4.1.5_3 
+universal (4-way universal) installed. If I uninstall gsed, or  
install gsed (non-universal), or install gsed+universal (2-way 32-bit  
universal), there is no problem compiling php5 (which I'm not  
compiling universal, by the way). I also reproduced the issues on a  
second computer, a MacBookPro2,2.

I tried switching gsed to the muniversal portgroup but that didn't  
have any effect. So there must be some serious 64-bit issues going on  
in gsed. We should probably switch gsed to the muniversal portgroup  
and list only i386 ppc as the supported architectures, until it can  
build a properly-functioning 64-bit binary. I filed a ticket:
