Count of Parsed field added to next record in dataset

Found an issue with the OSS versions between our Old and New Dev environments. Below are the details:

“Old Dev” has ECLWatch at 10.144.140.19 (internal_5.4.10-1)

“New Dev” has ECLWatch at 10.144.162.1 (internal_6.4.8-rc1)

Sample code:

setDs := dataset(['1,2,3', '4,5,6', '7,8,9'], {unicode num_set});

pt := project(setDs,

              transform({recordof(left), integer set_cnt},

                        self.set_cnt := count(XCR_Utilities.ConvertRCIUnicodeList.toIntegerSet(left.num_set)),

                        self := left));

output(pt, named('pt'));

The issue I am seeing is that in old dev the desired output should just count the number of items in each set, ie:

record 1 - count(1,2,3) = 3
record 2 - count(4,5,6) = 3
record 3 - count(7,8,9) = 3

But what im seeing with the new OSS version is the following:

record 1 - count(1,2,3) = 3
record 2 - count(4,5,6) = 6
record 3 - count(7,8,9) = 6

As you can see the set_cnt is not correct and almost looks like it added the content counts from record 1 to the count of the contents from record 2. Then for record 3 the count of the contents are added to the counts for record 2. I have other examples with show it’s the buffer not being cleared as well for the counts.

When doing each of the records individually, ie XCR_Utilities.ConvertRCIUnicodeList.toIntegerSet(setDs[1].num_set), the results come back correct.
