[Caml-list] debugging memory leaks
Chris Waterson
What tools or techniques do people use to track down memory leaks?
Minimally, is there a way to enumerate the live objects in the heap?
I've tried "valgrind" on a natively-compiled executable, but all the
"real" allocations are hidden in the Caml heap, so it's not very useful.
Any recommendations would be warmly welcomed. Thanks in advance...

There's ocaml-memprof, a compiler patch that adds memory profiling
features to ocaml programs;
Latest update of the patch itself, as far as I know:
http://www.pps.jussieu.fr/~smimram/docs/ocaml-3.09.3-memprof.patch
Readme:

Wow. This is fantastic!
I had to hack the patch a bit since I'm using objects in a handful of
places, but this is exactly what I needed.
Thanks a ton!

ocaml-3.07,but there is not a single reference/credit to it on this
page... Given the inheritance, the maintainer should be careful to
keep the original author's name.

Since I put the patch on my webpage I owe you an apology. If I remember
well, I got the link on IRC while having issues with memory and the only
thing I did was to resolve the conflicts generated by diff. I put it on
the net because it was hard to find and apparently it was useful to
other people. I'm correcting the credits right now.
Regards,
Samuel.

I know this is an old thread, but I have revised the memprof patch to work
with ocaml-3.11.2. Please let me know if there is a maintainer who would
like to look this over and/or distribute it. Otherwise, I'll put it up on
github or google code. Thanks,
Warren

I think something like github / google code is a very good idea, then
someone can pick it up at a later date when they need it.

You could consider, putting your code on
http://forge.ocamlcore.org
This is probably the place where it will have the best visibility for
other OCaml developers.
