Whatever the problem is, It's certinaly not compiling. I'd agree with Zombie today.
I've killed a compile before simply with a leaky map, which swamped the compiler in it's verbose state. When I fixed the leak, the compiler survived. Try big-blocking your map and trying re-compiling bits of it.
Of course, it could still be something else at fault: unless it's some painfully simple human error (like spelling the compile path wrong), the only other answer is to back-track your steps untill you can compile successfully.
