Oh, you just found a bug in the VFS :-). Thanks !
reply_ctemp() is a *really* old DOS-style call
that no modern clients do.
So we have a mix here of local (mkstemp) and
VFS-vectored calls, which will never work.
Currently I'd justmark base.open.ctemp as
knownfail until we decide how to fix this
properly. It's not a bug in your VFS code
