travis oddity under php 7

Hi Folks:

I'm undergoing peace negotiatons between DB and PHP 7.  Pretty much
done.  (Syria is next.)  But I've run into some strange things with the
unit tests on Travis CI.  The --SKIPIF-- section doesn't work under
PHP 7.

I put the following in driver/21freeResult.phpt
die("skip for everyone, note that phptype = $dbh->phptype");

Under PHP 5.6 on Travis CI it skips as expected:
https://travis-ci.org/pear/DB/jobs/92308330
SKIP DB_driver::freeResult[tests/driver/21freeResult.phpt](reason: for
everyone, note that phptype = mysqli)

Under PHP 7 on Travis CI the test executes:
https://travis-ci.org/pear/DB/jobs/92308331
FAIL [25/25] DB_driver::freeResult[tests/driver/21freeResult.phpt]

On my local machine running PHP 7, it skips as expected.

Any ideas?
