There is a fan on top of the heat sink so I have no idea what the speed 
of the chip is. Should I check?

I seriously doubt they doubled the speed of the memory bus. It would 
result in way to many failures and dissatisfied customers. The clock on 
the motherboard is still the same as before. This thing just plugs into 
the cpu socket.

Wouldn't slow memory cause problems elsewhere? And why only with the 
gcse (global common sub-expression elimination) optimization? I would 
have also expected both segfaults and/or compilation failures caused by 
garbled output from various passes.

They are 16M 30 pin simms. I'm not saying it isn't a memory problem. But 
  I've never seen one so specific.

What's a PP&S?
