> 34 months ago, [review 4541|https://reviewboard.asterisk.org/r/4541/] (ASTERISK-24917) resolved warnings raised by the compiler clang. However, because alternative/conflicting code paths exist, some warnings got missed. Here in this case, the storage for the app _voicemail_ was changed from file to IMAP via {{make menuselect}}.
> Then on FreeBSD 11.1, its default compiler _clang_ (4.0) reports:{code}warning: address of array 'vms->imapuser' will always evaluate to 'true' [-Wpointer-bool-conversion]
> warning: address of array 'vms->username' will always evaluate to 'true' [-Wpointer-bool-conversion]
> warning: address of array 'vms->context' will always evaluate to 'true' [-Wpointer-bool-conversion]{code}two times each, resulting in six warnings.
