I am just wondering. I am currently hacking using clisp-1996-07-22 and
it seems to have some problems:
- It seems to have a serve memory leak. Well, yesterday I was
wondering why a lisp session only five hours old had according to
ps(1) grew to 30MB. Even after I explicitly kicked out my own data
structures clisp reclaimed only about 1MB (after heavy trashing of
course -- the full garbage collection lasted longer than one
cigarette so the 30MB was not imaginary). The 1MB was approx the
size of my data structure.
Then I took a brute force attack -- uninterning *all* symbols from
*all* my packages (and user), after another trashing the core size
reduced only by a couple of kilo words.
Then I 'rebooted' CLISP.
That the X server grows to 24MB easily is known, but CLISP?
Come on, tell me that CLISP o.k! Or do we start to write bad code
too, because C++ hackers do? :-)
- Sometimes CLISP dies badly with no appearing reason. Even
evaluating a symbol from the REP could do that. This could be
pretty nice my own code, but I am clueless here.
I would love to know if other people had similiar problems with 07-22.
On the weekend I'll try to get a reproducible example for the memory
leak. I have still the malloc implementation under suspect. [I have
an example -- my current project -- but it is pretty much too large
(~3000 lines) to say anything useful.]
Anyhow, in the meantime I'll switch back to 05-30 to get work done.
I am not in the mood now to do C hacking.
Wish you a good hack,
PS. No, I am not telling what my current project is, because all of you
would laugh. Anybody want to try a guess? :-)
