I have noticed what appears to a memory leak, because I use both Bison and
the program it generates as plugins to an IDE (Integrated Development
Environment), and if I compile a lot, eventually the IDE runs out of
memory. I then have to restart the IDE.

-- I thought it was Bison itself that was leaking, but it interesting that
you have found that the parser program that Bison generates is leaking.
