Description:
When using mysql_fetch_fields(), the the client lib skips every other field in the array, eventually 
causing a memory access error. When using mysql_fetch_field() the field_type does not report 
correctly.

How to repeat:
//if (fieldNames) [fieldNames release];
unsigned cnt = mysql_num_fields(res);
field = mysql_fetch_fields(res);
unsigned j;
myFields = malloc_zone_malloc(mallocZone, sizeof(int) * cnt);
myFields = malloc(sizeof(int) * cnt);
//unsigned cntr = 0;
//fieldNames = [[NSMutableArray alloc] initWithCapacity:cnt];
for(i = 0; i < cnt; i++)
{
	//NSString *name = [[NSString alloc]  initWithCString:field[i].name];
	myFields[i] = field[i].type;
	printf("Field %u = %s, type = %i" , i, field[i].name, myFields[i]);
	//[fieldNames addObject:name];
	//[name release];
}

Suggested fix:

Can you please provide a complete compilable example that
shows the problem and make sure that this is not a problem 
in your code?
