      • Well. This error doesn't make too much sense to me ... it's shown with the /WP64 switch. (wchar_t is set to non-native, ie unsigned short) How is it possible that the compiler warns about "from 'size_t' to 'size_t'" ... thanks!

We've tried the code on Athlon, P4 and Core Duo processors and VS2005 Pro, Std and Express with the same result. The code should be used in a newly created Windows console app in C++. The problem occurs only under R
