[Developers] [ADMB Users] memory allocation error

[Mark Maunder]

Good topic for the ADMB developers workshop. I would like to get debugging working as well to find out why the sd report is not created when there are no Hessian errors.

We probably need a developers guide that describes the following


1)      How to download the source code from the SVN

2)      How to link the source code with your model and compile it

3)      How to set up debugging

4)      Tips on how to debug ADMB code

5)      Guidelines for formatting source code

Subject: [ADMB Users] memory allocation error

I have a memory allocation error. I found Dave's response to this problem in the past.
http://groups.google.com/group/admb-users/browse_thread/thread/bfdc7a95371c9bf6/1e5f21e161033c20?lnk=gst&q=memory+allocation+error&pli=1

However, I was hoping to get some of the gaps filled in.
Dave says
"If you compile your program in debug mode and put a breakpoint in ad_exit()
and do a stack trace you can find the line where this is happening. It may
be that you are doing something like trying to allocate a vector where
one of the arguments is uninitialized. "

Broken down into steps this is:
(1) compile your program in debug mode
I know this means to compile code with option -g and execute it as gdb --args ./
(2)put a breakpoint in ad_exit()
(3)do a stack trace

Could someone please elaborate on steps (2) and (3) for me?

thanks,
Mollie
