Just the other night, I was reading "Dune: House Atreides". In it, young Leto is
told by his father the Duke "When faced with a set of problems, solve the ones
that you can first. Then reassess the those that remain". Or something like
that.
With the problems (leaks) that you have, there's one that is easily identifiable
and fixable. So solve that one first and see what happens with the other leaks.
The case I'm talking about is the fifth block on the list. This is identified
as a form. I'm assuming that it's your form. So close it before you quit your
application (I think the solution oft-recommended on this e-mail list is to call
FrmCloseAllForms).
After doing that, see if there are any more leaks left. If so, then use the
debugger to examine their contents. You might recognize them and find out where
they were created and leaked.

Subject: Please help me with my memory leaks
Help! <grin> I've been working on an application for the Palm using
POSE. The application is running well in general, but is reporting
memory leaks when switching back to the launcher. I've spent a lot of
time looking for the leaks, but I can't seem to find anything in my code
that is causing this problem. I'm wondering if anyone on the list can
offer any advice. The heap dump from PalmDebugger is below and any help
in interpreting its output would be appreciated. The specifics of my
configuration are:
- POSE 3.0a5
- PRC-Tools 2.0
- Emulating Palm V
- OS 3.3 ROM with debug
- POSE is reporting that the owner ID is #2
Thanks in advance to anyone that has thoughts...
