 From all of our experiments, the difference between icc and gcc is actually 
quite small (at best a few percent). I wouldn't worry about it.

Yes, probably. (It may be that you don't have to reinstall p4est because it's 
just a C library, but it may be easiest to just do that as well.)

But I don't see why you need to switch to gcc. I believe that the compiler 
just ran out of memory. You may as well just try to compile everything again 
with, say, 'make -j1' and see whether that makes the compilation succeed.
