I built php with generic options 
./configure --prefix=/usr/local --with-openssl
rinning 'make test' leads to consuming 4 CPU cores and all available RAM

Test script:
./configure --prefix=/usr/local --with-openssl
make test

I can't reproduce this on WSL running Debian 9.5.  However, the
earlier tests also pass for me.  Please provide the .diff files of
the reported failing tests.

Thanks!  The OpenSSL version *might* be the problem, but since a
while we're running our Travis CI on Xenial which, I believe, has
also 1.0.2g.  However, the tests are slow[1], which may cause the
timeout for you.  Chris, since you've introduced the new
server/client test harness[2], do you have an idea?

Also, the new reneg_* options[3] that are available as PHP 5.6.0
are not yet documented (not even in the migration guide).

Is this still an issue for you with any of the actively supported
PHP versions[1]?  I would expect that OpenSSL 1.0 is no longer in

Actually, no, it's not an issue after 3 years, I am not even sure if it worth to check it out.
