Summary: VMS-Alpha abend using CURLOPT_HTTPHEADER

Initial Comment:
I have a C application written on VMS-Alpha version V7.2-1 that uses curl to Post to a URL. I'm having a problem overriding an http header field that Curl defaults. Curl defaults content-type in the http header to "application/x-www-form-urlencoded". My application is trying to pass XML in the body of the Post. Here is the Post with the default header fields not including my XML:
POST /SXC-RxExpress/AuthenticatingXmlServer.aspx HTTP/1.1
Authorization: Basic JHhjNHgzcHIjc3M6JHVyMyRjcjhwdCQ=
Host: staging.surescripts.net
Accept: */*
Content-Length: 1228
Content-Type: application/x-www-form-urlencoded
Expect: 100-continue

I subsequently wanted to change the "Content-Type" header to "text/xml", I am using the following code to do that in my application:

struct curl_slist *m_headerlist;
m_headerlist = NULL;
m_headerlist = curl_slist_append(m_headerlist, "Content-Type: text/xml");
.
.
curl_easy_setopt(pCurl, CURLOPT_HTTPHEADER, m_headerlist);
.
.
curl_slist_free_all(m_headerlist);

Executing my application with curl version 7.19.4 produces the following abend:
%SYSTEM-F-ACCVIO, access violation, reason mask=00, virtual address=000000004C525543, PC=0000000000561D44, PS=0000001B

I also tried the same type setup with curl version 7.16.0 and I get a similar abend:

Message:
Since this works and has worked a long time for others it makes me suspect
that this is either a problem with your app or something particular in the
VMS environment. Any chance you can use a debugger or similar to figure
exactly why this happens?
