Hi,
in gambit 4.7.0, ##get-bytes-allocated! does not seem to exist:
$ gsi Gambit v4.7.0
##get-bytes-allocated!
*** ERROR IN (console)@1.1 -- Unbound variable: ##get-bytes-allocated! 1>
I found https://www.ohloh.net/p/gambit-c/commits/294211710 which says that this was added in commit a413e140b66d8f8fa379119176e94078edd09ce0 on 2013 Sept 12.
Was it removed on purpose or by accident?
