            Bug ID: 106747
           Summary: Regression: go version does not print a number in 12.x
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: go
          Assignee: ian at airs dot com
          Reporter: dilyan.palauzov at aegee dot org
  Target Milestone: ---

If my observations are correct, in the 11.x series go version printed a version
number, while in the 12.x series it prints:

$ go version
go version unknown linux/amd64

The unknown-version is printed on git commit a3bd980b9b146633e2 ( Daily bump.
20220814)

In the 11.x series it printed

$ go version
go version go1.16.5 gccgo (GCC) 11.2.1 20211010 linux/amd64

This is a regression.
