[jira] Updated: (AXIS2C-181) The engine segfaults when the msg ctx
is free'ed
[ http://issues.apache.org/jira/browse/AXIS2C-181?page=all ]
Nabeel Yoosuf updated AXIS2C-181:
---------------------------------
Attachment: diff_reader
On the inspection it was found that the reader gets free'ed twice. The attached minor diff prevents the segfault. I am having problem committing it to svn; please someone commit if for me.
Thanks!

> The engine segfaults when the msg ctx is free'ed.
