Thread: Why this code crash ?

Hello

i get this code from RYMOS : http://sourceforge.net/projects/rymos

Code:

unsigned int k_printf(char *message, unsigned int line)
{
	char *vidmem = (char *) 0xb8000;
	unsigned int i=0;

	i=(line*80*2);

	while(*message!=0) // 24h
	{
		if(*message==0x2F)
		{
			*message++;
			if(*message==0x6e)
			{
				line++;
				i=(line*80*2);
				*message++;
				if(*message==0)
				{
					return(1);
				};
			};
		};
		vidmem[i]=*message;
		*message++;
		i++;
		vidmem[i]=0x7;
		i++;
	};

	return(1);
};

i try to compile it with Dev-C++ , no any errors but when i run programme it's crash and show report problem (Windows XP)
