You could use a profiling tool such as google perf tools to see what's using 
the memory in the compiler, but that would require figuring out what the 
allocations in the compier are associated with in your source code, which 
wouldn't necessarily be easy.

Last I heard, it never releases _any_ memory, and the one attempt to fix that 
via a garbage collector tanked performance. It _is_ something that needs to be 
sorted out one of these days though.
