Compiling With Microsoft Compiler

[Derek Magee]

Hi,

I'm trying to get the simple program below compiled using microsoft 
visual c++ from the command line. It works fine with debug information 
included (/Zi), but with this omitted the program links, but crashes at 
runtime. I'm using the latest windows 64bit precompiled binaries on 
windows 7, MSVC 2010. Any thoughts? I'm completely stuck.

Thanks

Derek

=== Code ===
#include <openslide.h>
#include <iostream>
using namespace std;

int main(int argc, char* argv[])
{
     cerr << "Prog started" << endl ;

     if(openslide_can_open(argv[1])){
         cerr << "Can open" << endl ;
     }
     return 0;
}
