   Is there a GNU (or at least freely redistributable) version of malloc
   which at least keeps track of allocated and freed segments (similar to
   what SunOS's /usr/lib/debug/malloc.o does).

take a look at the moraes allocator, ftp-able from cs.toronto.edu as
pub/moraes/malloc.tar.gz. it is one of the nicest mallocs [of course
i am biased] one can find, and you will be able to read the code too.
it comes with the usual uoft [cnews-style] copyright.

from its README:

        The allocator is small, fast and space-efficient.

        It performs coalescing on frees.

        It has hooks for profiling, tracing and memory leak detection.

        It has very comprehensive and paranoid errorchecking as a compile
        time option, enough to detect most forms of heap corruption.

        Optionally, it attempts to be compatible with the proposed
        ANSI C Standard definition for the standard library functions
        malloc(), calloc(), realloc() and free(). By default, it is more
        or less compatible with existing Unix malloc() functions - some
        differences do exist. [Notably free(), cfree() returning void,
        realloc() not accepting a freed block]


hope this helps...	oz
