Matthew Topol resolved ARROW-7104.
----------------------------------
Resolution: Cannot Reproduce
This was likely fixed in an earlier version but never tagged as the issue
indicates they were using Arrow 0.15.1 and I am not able to reproduce this
issue currently.
[~rwhitcomb_nvidia] If you're still able to reproduce this on v8 feel free to
re-open this please.
> [Go] Unable to Resize/Reserve more space on ListBuilder after init

> Key: ARROW-7104
> URL: https://issues.apache.org/jira/browse/ARROW-7104
> Project: Apache Arrow
> Issue Type: Bug
> Components: Go
> Environment: mac
> Reporter: Richard Whitcomb
> Priority: Major
>
> When using the ListBuilder unless I reserve enough capacity on the initialize
> resize/init call I run into. Based on the code I would expect to be able to
> grow the list builder after the initial call to reserve capacity.

> offset int32 builder which is why you see that in the above stack.
