We put cout statements in the code during debug and found
that overflow did not occur because of the following code
in Util.cpp
The reset to a correct value must occur earlier than the
range of the int because of the modulo math in GetTickCount().
#ifdef PLATFORM_POSIX
int GetTickCount() {
struct timeval tv[1];
struct timezone tz[1];
memset(tz, 0, sizeof(tz));
gettimeofday(tv, tz);
return tv->tv_sec % 1000000 * 1000 + tv->tv_usec / 1000;
}
#endif

Excellent, thanks! That is it...
Anyway, I guess it is rather worth fixing this function and make it return dword. I believe this should do the trick:
dword GetTickCount() {
struct timeval tv[1];
struct timezone tz[1];
memset(tz, 0, sizeof(tz));
gettimeofday(tv, tz);
return (dword)tv->tv_sec * 1000 + tv->tv_usec / 1000;
}
Can you confirm?
