[MsVisualStudio] OsiClpSolverInterface crash in VS2008 x64

[Chris Bielow]

Hi again,

I meanwhile solved the problem and thought I let the curious reader know 
whats going on:

First of all: CoinMP-1.3.3 is fine for the x64 Windows compiler as it is 
(just derive solution files as usual).

The problem that led to the crash (strangely only in Release mode) were 
inconsistent compiler flags:
I used "/D_SECURE_SCL=0" in my library which links against the core 
COIN-OR libs. COIN-OR on the other hand uses the implicit default 
"/D_SECURE_SCL=1". Somehow this leads to very nasty stack corruptions.
The MSDN docu does not mention this might happen 
(http://msdn.microsoft.com/en-us/library/aa985965(VS.80).aspx).

greetings
Chris
