First, compile with -Wall (I assume you use GCC).

Could this be
return strcmp(&(((UU_Record*)a)->username),&(((UU_Record*)b)->username));
Because username is an array of characters but strcmp wants pointer to
char?

Maybe this would need to be
qsort(&data_list, 15000, sizeof(UU_Record), my_strcmp);
or even
qsort(&data_list, 15000, sizeof(UU_Record), &my_strcmp);
Since qsort wants pointers as well.
If this doesn't help I'm sure somebody who knows more than me (esp. Glynn :)
answers soon with right solutions.
