nginx + my module crashes only when ignore client abort = on

[gadh]

more info: when i use "ignore client abort = on" , the crash happens when
the client aborts the connection, BEFORE my subrequest handler is called, so
its unlikely this code causes the crash.
also, i send the subrequest to a configured url named "aaa_post/" which uses
the proxy module to send it to other server.
