an older Go version, the Go toolchain amends its defaults
to match that older Go version as closely as possible.
For example, when a Go 1.21 toolchain compiles a program,
if the work module's `go.mod` or the workspace's `go.work`
says `go` `1.20`, then the program defaults to `panicnil=1`,
matching Go 1.20 instead of Go 1.21.

Because this method of setting GODEBUG defaults was introduced only in Go 1.21,

Ativar um ambiente virtual também muda algumas outras coisas, mas esta é uma das mais importantes.

## Verificando um ambiente virtual

Ao verificar se um ambiente virtual está ativo, por exemplo com:

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```console

	_ = needUSize

	if needCSize || needHeaderOffset {
		return ErrFormat
	}

	return nil
}

	var buf [dataDescriptorLen]byte

	// signature, the value 0x08074b50 has commonly been adopted
	// as a signature value for the data descriptor record.
	// Implementers should be aware that ZIP files may be

Also for security reasons, only a limited set of characters are
permitted, notably alphanumeric characters and a few symbols, such as
'.', that will not be interpreted in unexpected ways. Attempts to use
forbidden characters will get a "malformed #cgo argument" error.

When building, the CGO_CFLAGS, CGO_CPPFLAGS, CGO_CXXFLAGS, CGO_FFLAGS and
CGO_LDFLAGS environment variables are added to the flags derived from
