>                 Key: BEAM-14237
>                 URL: https://issues.apache.org/jira/browse/BEAM-14237
>             Project: Beam
>          Issue Type: Bug
>          Components: sdk-go
>    Affects Versions: 2.37.0
>            Reporter: Maksim Gaiduk
>            Priority: P2
>
> 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.
>  
> Go version: go1.18 darwin/arm64
