Wow, 700kB of source in one function? No wonder it takes ages! Some
of the internal algorithms are probably O(N^2) (or worse!) in the size
of the function.


The Sig11 is almost certainly due to running out of memory during the
optimization pass as it tries to build enormous flow graphs etc.


Either buy a faster/bigger computer, turn off optimizing, or break it
into many smaller functions.
