strtok_r strange failure

Hi

I have thins strange failure in strtok_r() on NetBSD-6.1.2/amd64

Breakpoint 1, load_descriptor (xmlnode=0x7f7ff7bdd680, 
    provider=0x7f7ff7b05400, role=LASSO_PROVIDER_ROLE_IDP) at
provider.c:356
356             LassoProviderPrivate *pdata = provider->private_data;
(gdb) n
358             int counter = 0;
(gdb) 
361             value = getSaml2MdProp(xmlnode,
(gdb) 
363             token = strtok_r((char*) value, " ", &saveptr);
(gdb) print value
$1 = (xmlChar *) 0x7f7ff7bc63e0 "urn:oasis:names:tc:SAML:2.0:protocol"
(gdb) n
364             while (token) {
(gdb) print token
$2 = 0xfffffffff7bc63e0 <Address 0xfffffffff7bc63e0 out of bounds>

token is almost correct: only the upper 32 bytes are wrong. Any idea of
what is going on?
