Key: AXIS2C-181
URL: http://issues.apache.org/jira/browse/AXIS2C-181
Project: Axis2-C
Type: Bug
Components: xml/parser
Versions: 0.92
Environment: All
Reporter: Nabeel Yoosuf
Fix For: 0.92
The engine segfaults when the msg ctx is free'ed.
this happens when freeing the following in sequence.
msg_ctx->envelope->payload->reader. This scenario has not been seen so far
since the payload was never built through the reader.
Strack trace is attached.
Program received signal SIGSEGV, Segmentation fault.
