Matthias, from what I can see you have some experience with this part of IfConversion.cpp. Perhaps you could give some advice on or even fix this problem? In short, a bug in IfConversion was found and fixed, but when patch was applied, we ran into a problem relating to Redefs - see above.
I am now on vacation, and cannot not fix IfConversion right now, so if anybody could take the time that would be great, as this is a bug that should be fixed ASAP.
