asterisk users - Mar 2014 - Any help Address 0xfffffffe out of bounds in app_confbridge.casterisk-11.5.1 using confbridge.conf

Address 0xfffffffe out of bounds why and how to 
solve.MyConfbridgeCount(conferencenumber,variablename )return total number 
of user in conference given by conferencenumber otherwise zero.At runtime 
using MyConfbridgeCount(4000,count ).now app2: MyConfbridgeCount will call 
function count_exec(struct ast_channel *chan, const char *data).But at 
compile time char * data cause core dumped. Asterisk-11.5.1 Centos6

Please discontinue spamming the users list with your posts.

Not receiving an answer to your question is not a reason to repeatedly
post (four posts now in the past few days?)

I've already responded to your original post and asking you to post on
the issue tracker and follow the issue guidelines to provide the
information needed to investigate the crash.
