[~tuxian] I'm fairly certain I found the primary cause of the memory corruption.  Ironically, it turns out to be a hole in the original fix patch on ASTERISK-26344 which was fixed in the patch that got committed.  However, I think there is another potential for corruption that is fixed by [^0007_jira_asterisk_26516_v13_free_mem_fix.patch].

# From a clean workspace apply the three patches
# Run your DNS test with MALLOC_DEBUG.  It should be able to go overnight.

I expect the memory leak was another symptom of the bug that was also causing the primary memory corruption.

Please test and report back.  Thanks.
