I use Fedora core 4 to develop this code.  The version of ScriptStringAnalyse you have does not actually do anything other than return various values.  The problem occurs after the second call to ScriptStringAnalyse but the only difference is that hdc is specified.  In theory it should drop through to the return E_NOTIMPL.

I think there are a couple of choices: you could fire up winedbg, set a break at ScriptStringAnalyse and step through the function; or  you could apply my last patch and see if the problem goes away (unsatisfying but expedient).

Do you have the trace WINEDEBUG=+uniscribe wine usp10_test.exe?  It may
help withmailing down where the problem is.
    

Trace attached. This machine is a Fedora development installation
b.t.w, my other machine runs Kubuntu Dapper and it doesn't show the
problem.
