P2 Description
Reproducible example:
reproducible.go: https://pastebin.com/raw/LqADath4
go.mod: https://pastebin.com/raw/qXmyh62N
run cmd: go run reproducible.go --output output.tsv
On lines 29-31, the program is supposed to read from rowIter function only while new data is available (this is standard interface to read input after GroupBy operation).
Instead, the cycle runs indefinitely. In gdb/debug prints it can be clearly seen that program just steps through the "if !b" block when "b" is false.
Supposedly this is the cause of UB from ABI function call inside beam.
