Minor Description
TSHttpTxnConfigIntSet and Get use _conf_to_memberp to get a pointer to various fields, and then access it as a 32bit int. But many of the fields are now bytes. A fix would be to make _conf_to_memberp return the type properly, and make TSHttpTxnConfigInt* access the field as the proper size.
I saw valgrind complaining about uninitialized data from the code (which is probably because of padding in the structure, since it is cleared a field at a time), but there are probably much worse effects around reading and writing unrelated fields.
