Note: the warning here suggests that the core file is from a 
different executable.  The backtrace provided is likely incorrect.  
Try to reproduce the problem with the current executable to get a 
proper backtrace.

It might be also be a good idea to look into "nginx -V" output and 
the configuration (first of all, to make sure there are no 3rd 
party modules used; if there are any - try to reproduce the 
problem without them), as well as to check if you are able to 
reproduce the problem with the latest mainline version.
