Got this calling iter.Next()

I found another gojq goroutine running

github.com/itchyny/gojq.normalizeNumbers({0x1b3b180?, 0xc00083bad0?})
        /Users/bryan/go/pkg/mod/github.com/itchyny/gojq@v0.12.8/normalize.go:77 +0x105

        /Users/bryan/go/pkg/mod/github.com/itchyny/gojq@v0.12.8/compiler.go:38

Starting with line 884 in func.go

case map[string]interface{}:
    return v[x]

Starting with line 76 in normalize.go

case map[string]interface{}:
	for k, x := range v {
		v[k] = normalizeNumbers(x)
	}
	return v

Looks like the code is reading a map that can also be written to at the same time.

You should not run a gojq query with the same input value.
