Description:hi

I'm not sure why, but app_queue keeps crashing. I have had two crashes in app_queue.c:501 and one in app_queue.c:666 (EVIL!) the latest week, and I cannot understand why. Backtraces are attached. I've looked through the logs, but I can't find _anything_ and full debug logging is always enabled to another box with enough diskspace... I haven't tried later than 1.2.10 yet, but AFAICS from the -svn lists, no relevant changes exist.

1. Was asterisk built with 'make don-optimize'
2. Please do try to reproduce this on 1.2.12.1

I changed to -O0 in the Makefile

I'll try to reproduce it with 1.2.12.1, but I really don't see why it should matter, since I can't find any updates of relevance....

the modifcations you are making to one makefile don't have the same effect as make don-optimize

please recompile after select this from the menuselect menu. and submit the backtrace(s)

thanks,

the modifications do indeed have the same effects unless there is some really nasty magic around. From the makefile

ifneq ($(findstring dont-optimize,$(MAKECMDGOALS)),dont-optimize)
######### More GSM codec optimization
######### Uncomment to enable MMXTM optimizations for x86 architecture CPU's
######### which support MMX instructions.  This should be newer pentiums,
######### ppro's, etc, as well as the AMD K6 and K7.  
#K6OPT  = -DK6OPT

#Tell gcc to optimize the code
OPTIMIZE+=-O6
endif

...and further down

dont-optimize: install

meaning when I changed OPTIMIZE+=-O6 to OPTIMIZE+=-O0, this has the very same effect

is there anyway you can provide us with a core dump file .. or information on what the values being passed to strcasecmp are?  this would be a huge help is tracking down the source of this issue some. atm i can't figure out of some of the pointers being returned AST_LIST_TRAVERSE are correct or not and having this information would be a huge help.

MAYBE related to M7818. Not 100% sure...
By: Anthony LaMantia (alamantia) 2006-09-28 15:08:47

also posting any debug logs you may have would also be very helpfull is iron'ing out this issue.
By: Roy Sigurd Karlsbakk (rkarlsba) 2006-09-29 06:56:51

It is probably related to, or quite possible the same bug as 7818, since it occured right after a reload

rkarlsba: jsmith is reporting in 7818 that the issue appears to be resolved. I think Kevin's commit may have also contributed http://lists.digium.com/pipermail/svn-commits/2006-September/017331.html. Can you please check out the latest 1.2 branch code?
By: Anthony LaMantia (alamantia) 2006-10-09 11:44:24

Hello,

Did updating to the latest subversion release resolve this problem for you, or do we need to continue our investigation into the issue?
By: jmls (jmls) 2006-11-02 12:55:46.000-0600

rkarlsba, 7818 has been closed because the problem described in there was fixed. As previously mentioned, could you please retest against the latest 1.2 code ? thanks
By: Roy Sigurd Karlsbakk (rkarlsba) 2006-11-03 03:44:30.000-0600

Problem seems to be solved. Please close this. Thanks :)
