Yes, that package looks good. Two nice things in 5 minutes:
if( !this ) return 0;
I would like to read "references are needless" into that.
// C++ bug (Action)
Yes! That is exactly my gut feeling, too!
Interestingly it seems that it has been possible to apply access
policies on file level, even for preprocessor things etc.:
#define PADS_VERSION 0x851021 /* YYMMDD */
#define CARTE 0x80
#define NUMERIC 1
That i never had seen before.
Quite a lot of C++ in this package..

In V10 there are the sources of cfront, and also troff, pic etc.
I would wish i had more time to look through that. Most code
from these laboratories and universities is just casual, this is
what i like so much. I mean, really. Most of the elder code goes
and is done with it When i started, as well as today, notational
things for namespace and (get, set) functions were in use for at
least libraries, and then i found C++ preferable over C due to
"using NAME" directives etc., whereas in C you go for
g_mount_tracker_find_by_mount_spec() and woe if the argument is "a
subclass". And pi is really a debugger!? I detest debuggers!
But he instrumented most of it with trace() and VOK by hand in
order to debug that thing. That is fantastic. I dislike so much
that today shipout code of even the smallest utility is compiled
with stack canaries enabled, the assembly looks infested, all that
should be kept in debug code, in my opinion.
