gocyclo linter is not executed when other linters enabled

GolangCI-Lint version: 1.3.6
Go version: 1.10

I've noticed that when using default configuration (i.e., default set of linters) and enabling gocyclo both using command line arguments or .golangci.yml, gocyclo is actually not running or it can rarely give one output (although I know it should output a ton of warnings).
Looks like something interrupting it's work.
So I've tried to disable all the linters (including enabled by default) but left gocyclo enabled and it started to work like a charm.
Then I enabled govet and gocyclo continued to work correctly.
But when I was trying to enable some other linters from default linter set, gocyclo went back to incorrect work (or no work at all, to be precise).

Here's the config:

linters:
    enable:
        - gocyclo
    disable:
        - errcheck
        - staticcheck
        - unused
        - gosimple
        - gas
        - structcheck
        - varcheck
        - ineffassign
        - deadcode
        - typecheck

linters-settings:
    gocyclo:
        min-complexity: 5
    golint:
        min-confidence: 0
    govet:
        check-shadowing: true
    maligned:
        suggest-new: true

issues:
  exclude:
    - should have a package comment
    - declaration of "err" shadows declaration

thank you for the issue,
fixed it in #46, check, please
