<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">So, I think the actual log message fix is okay.
This, however, is *** dangerous ***
While MALLOC_DEBUG is a build option used for debugging purposes, this still essentially adds what amounts to an auto-DOS command to Asterisk. Toss in the number of people who expose the 'command' class authorization on their AMI accounts, and you have a recipe for something frightening.
I'm potentially fine keeping it in as a handy 'test that you system can survive running out of memory' - but if so, let's just #ifdef 0 the whole block.</pre>

I don't like this fix at all. But I like the problem even less.
If anyone has a better idea, do come forward. (Aside from fixing the problem that caused me to run out of memory in the first place. But that's for another day.)</pre>
