What version of Go are you using (go version)?

$ go version

go version go1.16.2 darwin/amd64

Does this issue reproduce with the latest release?

Yes, it reproduces in Go Playground as well.

What operating system and processor architecture are you using (go env)?

MacOS, 64 bit but this reproduces on Linux and Go Playground as well.

What did you do?

I have a program that has the same variable name nested four times and it seems that Go does not consider the last one for some reason. I am not sure if maybe this is just a bug with some type of compiler validation or linter.

You can see the behavior here:
https://play.golang.org/p/zNmdyH3Owl_W

What did you expect to see?

Global count: 1
Main count: 65
Nested count: 80
Nested-nested count: 82

What did you see instead?

./prog.go:29:5: сount declared but not used

				сount = 82

The first character here is not c:

# the character copied from your code
$ echo -n "с" | xxd
00000000: d181                                     ..
# the character typed manually
$ echo -n "c" | xxd
00000000: 63                                       c
