I was talking about linking, not compiling.

If you compile a large source file with optimizations, then it is
known that GCC sometimes consumes a lot of memory during
optimization.  21MB isn't too much, btw, I have seen examples of
innocent code which uses much more than that (some of those examples
were posted here in the past).  One particular case is when a program
includes initialization of a large array or data structure.

The best way to avoid this high memory usage is to split the offending
functions into shorter ones.
