WSMethodInvocationAddSerializationOverride(fRef, CFStringGetTypeID(), _stringToXML, NULL);

My serialization function is trivial:

static CFStringRef _stringToXML(WSMethodInvocationRef invocation, CFTypeRef obj, void *info)

{

if ((CFGetTypeID(obj) == CFStringGetTypeID()) && ![(NSString *)obj isEqualToString:@""])

{

NSString *result = [[NSString alloc] initWithFormat:@"<%s>%@</%s>", "%@", obj, "%@"];

return (CFStringRef)result;

}

return NULL;

}

I'm using WSMethodInvocationInvoke to call a SOAP web service, which works with no problems except one case: where the parameter array contains strings with UTF-8 characters. The crash is occurring deep within CFNetwork:

This is my code for creating and invoking the SOAP method call (error handling omitted):

NSDictionary* headers = [NSDictionary dictionaryWithObjectsAndKeys: soapaction, @"SOAPAction", "text/xml; charset=utf-8", @"Content-Type", nil];

fRef = WSMethodInvocationCreate((CFURLRef) url, (CFStringRef) method, (CFStringRef) kWSSOAP2001Protocol);
WSMethodInvocationSetProperty(fRef, kWSHTTPExtraHeaders, headers);
WSMethodInvocationSetProperty(fRef, kWSSOAPBodyEncodingStyle, kWSSOAPStyleDoc);
WSMethodInvocationSetProperty(fRef, kWSSOAPMethodNamespaceURI, Namespace);
WSMethodInvocationSetParameters(fRef, (CFDictionaryRef)params, nil);
fResult = (NSDictionary*)WSMethodInvocationInvoke(fRef);

The parameters look like this:

I have all of the debugging options set and I'm not seeing any warnings.

NSDebugEnabled=YES

NSUnbufferedIO=YES
MallocHelp=YES

MallocCheckHeapEach=100000
MallocCheckHeapStart=100000
MallocScribble=YES
MallocGuardEdges=YES
MallocCheckHeapAbort=1
CFZombie=5

Any ideas how to fix it?
