Problem with debug IDE displaying value of __int64

[Guest]

I get odd behavior in the debugger with the following code. The output of
the program itself is correct, but when I add the g_bad_int64_max and
g_bad_int64_min to the watch window they show values of -1 and 0
repsectively. This only happens when initializing a const __int64 in global
scope with a literal constant. I fooled around with the initial value and it
looks like the upper 32 bits are being ignored. Is this a known issue?

#include <iostream>
#include <limits.h>

using namespace std;

//This is displayed incorrectly in debugger
const __int64 g_bad_int64_max = LLONG_MAX;
const __int64 g_bad_int64_min = LLONG_MIN;

// This works
__int64 g_int64_max_initializer = LLONG_MAX;
__int64 g_int64_min_initializer = LLONG_MIN;
const __int64 g_good_int64_max = g_int64_max_initializer;
const __int64 g_good_int64_min = g_int64_min_initializer;

main()
{
// This works
const __int64 my_int64_max = LLONG_MAX;
const __int64 my_int64_min = LLONG_MIN;

cout << "\n g_bad_int64_max: " << g_bad_int64_max
<< "\n g_bad_int64_min: " << g_bad_int64_min
<< "\n g_odd_int64_max: " << g_good_int64_max
<< "\n g_good_int64_min: " << g_good_int64_min
<< "\n my_int64_max: " << my_int64_max
<< "\n my_int64_min: " << my_int64_min
<< endl;

}

It's a bug in VS2003. This is fixed in VS2005.

Thanks,
