your post gave me the idea to profile the memory usage of the generated
binary with valgrind.

In this release of jhc, the problem is handled in a quite radical way.
It seems that no free() is ever emitted, the allocated heap memory is
not released.
Well, this classifies like a bug, I guess.

On the bright side, when I removed all memory deallocation from the C
version, supposing (naively maybe) that it would radicaly reduce the
difference in performance, jhc's still ran twice faster.
