1: GCCGO

At command line I typed gccgo -v and it spits out 9.2.0

Thanks for the report.

The "what did you do" section of your report does not show what you did. It just shows the result of the command (a compiler crash). I'm guessing you are building github/apache/thrift with gccgo, but please confirm this to facilitate the investigation of the issue. You should provide a complete and autocontained list of steps (in the form of terminal commands) that can be used to reproduce the crash. Thanks.

Yes I use github/apache/thrift with gccgo 👍

Thanks for filing this bug. It looks as though it was discovered independently (see issue 33871 and Ian has submitted a fix. With a tip version of gccgo I was able to successfully issue

go get github.com/apache/thrift/lib/go/thrift/...

So I am going to assume that this fixes your issue.
