What OS do you use? This problem should be related to Windows XP/Server 
2003.

Does you dummy host application in C use implicit TLS?

Do C and D DLLs attached to this post behave differently for you 
regarding to TLS initialisation (load and call `getTLSIndex` and 
`getTLSVarValue`)?

I'll try to help but I need full test suit to see where is the 
difference between C and D DLLs.
