Reduced testcase:
void set_color(void);
void xml_colorize_line(unsigned int *p, int state)
{
    int c;
    switch(state) 
    {
        case 1:
            goto parse_tag;
        case 2:
            goto parse_comment;
    }
    for(;;) 
    {
        c = *p;  
        if (c == '<' && state == 0) 
        {
parse_comment: ;
            while (*p != '\n') 
                state = 3;
parse_tag: ;
            while (*p != '\n') 
                state = 0;
            set_color();
        }
        else
            p++;
    }
}
