Have you come across the memory smashing exploit? I can't remember much 
about it, but if you can hammer memory in your own VM, you can actually 
corrupt memory in the next door VM. Even worse, you can control the 
corruption with the intent of hacking into the VM!

I'm pretty certain there are proofs of concept out there. So I guess gcc 
might be doing exactly that by accident to cheap memory (my RAM is the 
"value" brand - paid about £13 per 4GB stick). When I think back the 
first memory I ever bought was £50 for a 32*M*B stick :-)
