If I use gss_init_sec_context (rel 1.6.1) to create a gssapi token with
gss_mech set to
static gss_OID_desc _gss_mech_spnego = {6, (void
*)"\x2b\x06\x01\x05\x05\x02"};
gss_OID gss_mech_spnego = &_gss_mech_spnego;
I have the below memory leaks. If I use gss_mech = GSS_C_NO_OID I don't have
any leak. Is this a known problem ?
major_status = gss_init_sec_context(&minor_status,
GSS_C_NO_CREDENTIAL,
&gss_context,
server_name,
gss_mech,
0,
0,
GSS_C_NO_CHANNEL_BINDINGS,
&input_token,
NULL,
&output_token,
NULL,
NULL);
