I recompiled Ruby 1.6.5. with a modified rb_compile_file, but I can see no
difference,
the loss of memory remains the same.

NODE*
rb_compile_file(f, file, start)
    const char *f;
    VALUE file;
    int start;
{
    char *tmp = ALLOCA_N(char, strlen(f) + 1); // +++
    lex_gets = rb_io_gets;
    lex_input = file;
    lex_pbeg = lex_p = lex_pend = 0;
    ruby_sourceline = start - 1;
    strcpy(tmp, f);                                // +++
    return yycompile(tmp, start);           // +++
    // return yycompile(strdup(f), start); // ---
}

But your code gives me new ideas where to look.
I modified my samples once more, to see, whether the loss already appears
during compilation.
And the loss also appears in the following situation:

# demo-bug.rb
counter = 0
while TRUE
        counter = counter + 1
        begin
                load "loadit-bug.rb"
        rescue Exception
        end
        puts "Round #{counter}" if (counter.modulo(100) == 0)
        GC.start if (counter.modulo(500) == 0)
end
# end of demo-bug.rb

# loadit-bug.rb
rabbel
# endof loadit-bug.rb

Thanks anyhow,

Jens
