Some strange winedbg regression...

[Eric Pouech]

> So I was wondering how to debug this ? I tried to attach 'gdb' to it (and it

load miscemu/wine in gdb, it'll get what you're looking for

if it doesn't work better you can also try the attached patch (if the 
bug is triggered inside the debugger, otherwise - in some builtin DLLs, 
or in wineconsole - it won't help at all)

A+
