Hello,

i hacked wine/dlls/ntdll/signal_i386.c:set_cpu_context to see how far it gets.

739     if (flags & CONTEXT_FULL)
740     {
741         if ((flags & CONTEXT_FULL) != (CONTEXT_FULL & ~CONTEXT_i386))
742             FIXME( "setting partial context (%x) not supported\n", flags );
743         else
744             __wine_call_from_32_restore_regs( context );
745     }

In this case i ignored the partial flags 0x13: CONTEXT86_CONTROL |
CONTEXT86_INTEGER | CONTEXT86_DEBUG and called
__wine_call_from_32_restore_regs() right away.
Restore the missing CONTEXT86_SEGMENTS seem to have no negative effect at all.

To fix this right, __wine_call_from_32_restore_regs (e.g.
relay.c:BuildCallFrom32Regs(void) needs implement partial context stuff.

Maybe full context restore even if partial requested could be made default.
Yet to see what kind of app bumps on this...

Ok. It got further with context "hack".
Hangs in RPCRT4 (had to CTRL+C).

wine/dlls/secur32/wrapper.c:MakeSignature gets bad stuff

---- snip ---
SECURITY_STATUS WINAPI MakeSignature(PCtxtHandle phContext, ULONG fQOP,
 PSecBufferDesc pMessage, ULONG MessageSeqNo)
{
    SECURITY_STATUS ret;

    TRACE("%p %d %p %d\n", phContext, fQOP, pMessage, MessageSeqNo);
    if (phContext)
    {
        SecurePackage *package = (SecurePackage *)phContext->dwUpper;
        PCtxtHandle ctxt = (PCtxtHandle)phContext->dwLower;
---- snip ---

"phContext" ok, "package" and "ctxt" both NULL

Attachment follows.
