I use tbb with:
Microsoft Development environment 2003 version 7.1.3088
Intel c++ compiler 9.0 (W_CC_C_9.0.030)
OS: windows 2000 5.00.2195, Service pack 4
first remark: I will not have fscanf_s (and the other security improved (sic!) functions). Never mind!
Second and more important: if I use the code added below (your code with a tbb function call, but the problem will come out with other functions), it compiles, it works inside the visual studio debugger, but it does not work if I call it from a console (in both the debug and release compilation). It only work if I do not add the tbb functions.
Is this a windows 2000 problem or a compiler problem?
As you can see, this is a big problem if somebody want to use intel compiler with tbb!
Any suggestion?
