[xmlsec] problem with raw-x509-cert

Leif,

Not sure which code you are looking at for the

This is how this code looks for me

int
xmlSecKeyInfoCtxInitialize(xmlSecKeyInfoCtxPtr keyInfoCtx,
xmlSecKeysMngrPtr keysMngr) {
    int ret;

    xmlSecAssert2(keyInfoCtx != NULL, -1);

    memset(keyInfoCtx, 0, sizeof(xmlSecKeyInfoCtx));
    keyInfoCtx->keysMngr = keysMngr;
    ....
}
