> I discovered this while working on something with don't optimize and malloc debug enabled. I can confirm that these warnings don't appear normally without malloc debug. Reproduction is simple:
> 1. run asterisk. type 'module load'
> 2. attempt to tab complete
> 3. watch the errors spew out at a rate of one per tab completed item
> error messages appear in the following form:
> WARNING: Freeing unregistered memory <address> by cli.c complete_fn() line 253
> If you add some characters to reduce the number of matches against tab completion, the number of error messages decreases.
> The problem does not occur in 1.8. It does occur in trunk r383579 (most recent version at the time of report) and in 11 r383601.
