Problems with fread_string

[Brian T . Johnson]

I'm fairly new to C, this is only the second function I've written by myself. 
Can someone more experience point out what I'm doing wrong? I'm really tired, 
so plz don't flame me if I forgot to include some info.

Thanks,
Brian

trying to read file: 
../data/sysinfo

File looks like this:
---
BEGIN
Flag AB
Strt 1010188897
Exec Halon~
Lcmd Bran[blackjack guard]~
END
---
read func looks like this:
void load_sysinfo( void )
{
        FILE *fp;
 
        log_string( "Loading system info..." );
 
        system_info.boot_time = current_time;
        system_info.startup_time = current_time;
 
        fp = fopen( SYSINFO_FILE, "r" );
 
        if ( !fp )
                return;
 
        for ( ; ; )
        {
            char *word;
            char buf[MSL];
            bool finished = FALSE;
 
            fread_to_eol( fp );
            word   = feof( fp ) ? "End" : fread_word( fp );
 
            switch ( UPPER(word[0]) )
            {
            case 'E':
                if ( !str_cmp( word, "End" ) )
                        finished = TRUE;
 
                if ( !str_cmp( word, "Exec" ) )
                        system_info.exec_by = fread_string( fp );***LINE 3242
                break;
 
            case 'F':
                if ( !str_cmp( word, "Flag" ) )
                        system_info.flags = fread_flag( fp );
                break;
 
            case 'S':
                if ( !str_cmp( word, "Strt" ) )
                        system_info.startup_time = fread_number( fp );

                break;
 
            default:
                fread_to_eol( fp );
                break;
            }
            if ( finished )
                    break;
        }
 
        if ( IS_SET( system_info.flags, MUD_SUSPENDED ) )
                REMOVE_BIT( system_info.flags, MUD_SUSPENDED );
 
//      system( "rm -f ../data/sysinfo > /dev/null" );
        fclose( fp );
        return;
