It's not surprising this takes more memory than GCC 2.95.3.
There's a very big function in this file, and GCC is now function-at-a-time,
meaning that we build a representation for the entire function in memory, rather
than compiling it one line at a time. That's not to say some improvements could
not be made, but this is a conscious design change. An increase in memory is
inevitable in light of function-at-a-time.
