Hello,

not really a problem but a bit annoying in trace logs and debugger.

In certain situations IClientSecurity::SetBlanket() causes in internal
exception due to a non-string parameter in FIXME.
Handled gracefully but still noise.

The .NET code passes "COLE_DEFAULT_PRINCIPAL" as pServerPrincName which is
defined as ((OLECHAR *)-1).

Code:

http://source.winehq.org/git/wine.git/blob/0ceee481fe16ac6f731f4cb13717d5b40...

--- snip ---
  98 static HRESULT WINAPI client_security_SetBlanket(
  99     IClientSecurity *iface,
 100     IUnknown *pProxy,
 101     DWORD AuthnSvc,
 102     DWORD AuthzSvc,
 103     OLECHAR *pServerPrincName,
 104     DWORD AuthnLevel,
 105     DWORD ImpLevel,
 106     void *pAuthInfo,
 107     DWORD Capabilities )
 108 {
 109     FIXME("%p, %p, %u, %u, %s, %u, %u, %p, 0x%08x\n", iface, pProxy,
AuthnSvc, AuthzSvc,
 110           debugstr_w(pServerPrincName), AuthnLevel, ImpLevel, pAuthInfo,
Capabilities);
 111     return WBEM_NO_ERROR;
 112 }
--- snip ---

Would be nice to avoid calling debugstr_w(-1) in that situation.

Regards
