Bill Mitchell commented on AXIS2C-795:
--------------------------------------
I can see where error 4 is being recorded. Unfortunately, this code is not
getting returned all the way to the client because of an issue I raised in
AXIS2C-791. After axis2_op_client_execute returns the error, when the code in
svc_client.c tries to reset the msg_ctx to null, axis2_op_client_add_msg_ctx()
replaces the error 4 with an uninformative error 2. When I apply the change I
described to op_client.c to remove the non-null parameter validation of the
message context, the error 4 is returned completely to the client application.
Adding the log message is nice. Thanks.

> In op_client.c, the function axis2_get_transport_from_url() is used to
> analyze the prefix to the URL. If the URL is malformed and does not contain
> a colon, the scan runs off the end of the url string.
> The loop that reads:
> start = url;
> end = url;
> while (end && (*end) != ':')
> end++;
> should read:
> start = url;
> end = url;
> while ((*end) && (*end) != ':')
> end++;
> I'll admit to coming across this by inspection while tracking another
> problem. I have not actually forced the seg fault, as the loop will usually
> find a colon somewhere in memory and return a very large transport string.
