[OpenSER-Devel] crash

[Dan Pascu]

Hi Juha,

Your crash looks suspiciously similar to mine, which I have posted at

https://sourceforge.net/tracker/?func=detail&atid=743020&aid=1912110&group_id=139143

If you look at that, you'll notice that it was also a result of 

... -> query_db_notify -> get_subs_dialog -> get_subs_db -> strlen

while yours had this stack trace:

... -> publ_notify -> get_subs_dialog -> get_subs_db -> strlen

Mine was triggered by refreshWatchers while yours by a SUBSCRIBE, but I 
believe they have a similar cause. Unfortunately I no longer have the 
syslog entries to check the error messages.
