Version of Golang used when building/testing:

• 1.11

• 1.15
• 1.16
• 1.17
• 1.18
• 1.19
• 1.20

How Has This Been Tested?

Unit tests on master fail on Go 1.22, but work on 1.21.
After the fix, both compilers are happy.

Narrowed it down to an internal panic in golang.org/x/tools, after upgrading to latest version of the lib and doing a go mod tidy, the crash went away. The lowest x/tools version that works is 1.13.
