Comments: | By: Serge Vecher (serge-v) 2007-02-19 14:25:41.000-0600 what about 1.2.15. If asterisk was not built with "make don-optimize", it needs to be rebuilt and bt redone. By: klasstek (klasstek) 2007-02-19 17:22:34.000-0600 Yes it will occur with 1.2.15 http://svn.digium.com/view/asterisk/tags/1.2.15/apps/app_meetme.c?r1=43891&r2=53682 Is the only change to meetme between releases. The steps to reproduce it can be used to verify the issue on any asterisk running as early as 1.2.9 - current 1.2.x which is as long as we've been having the issue. I've provided a patch that should protect just the instance that occured this morning, but a more thorough evaluation of that section of code must be performed by the maintainer to ensure that the rest of the code is safe from similar circumstances. I've recomplied with dont-optimize, but I also have my fix in place so I don't anticipate having the issue again. I may be able to revert during a maintenance window, but the bug can be independantly verifyed with the instructions provided. --Karl By: Serge Vecher (serge-v) 2007-02-20 09:14:43.000-0600 thanks for the note, Karl. By: Russell Bryant (russell) 2007-02-20 10:45:55.000-0600 The patch in 7647 should solve this issue. Thanks! |
