By: Kaloyan Kovachev (knk) 2006-07-26 09:25:18 I don't think there is something wrong with that patch, but with the replacments functions when MALLOC_DEBUG is enabled By: Kaloyan Kovachev (knk) 2006-07-26 11:05:05 not sure if it will be of any help, but commenting out the calloc macro in /include/asterisk/astmm.h (line 59) have fixed this one, but not 7484 on hangup asterisk didn't crashed, but at the cli and in mmlog there were lots of warnings, then i have reloaded extensions, which caused asterisk to crash. attaching the mmlog file in case it will be of any help. Up to line 67 (before the first appearence of 'ast_variable_destroy') are the warnings before 'extensions reload' By: Russell Bryant (russell) 2006-07-26 11:43:58 All of those warnings you see if your mmlog are because it did not know about that memory being allocated due to commenting out the macro in astmm.h. However, when it got free'd, it did go through the memory manager and it got upset. :) I am looking into this, as well as 7484, trying to reproduce it and figure out the best way to fix it.
