Hello,

some of those points can be confirmed since I integrated boost into our environment:

For 1: We do only have one boost version and both binaries do not use anything compiled from boost. No special flags have been set for the pre processor.

For 2: We do never mix debug runtime libraries and all libs do use the /MDd flag so that the dlls share the same runtime context.
But I will check that with dependency walker again.

Both binaries are build on the same machine by the same compiler. However the noted fact that the assembler code is different somehow bothers me since I cannot confirm that the binaries itself are build with the same compiler settings.
Anyway since I am in debug I do expect no changes there since we usually build debug without any optimization.

Thanks
Sam
