Comment (by TheDigitalOrchard):

 I saw a `bus error` when accessing my application via `php` at the command
 line. Via `php-fpm`, it was displaying a '502 Server Error`. I suspect
 both were the same crash happening at the moment openssl_* functions were
 being called.

 The code that was affected in my application was identical to what Comment
 #3 above has. If that code was never executed, the crash never occurred.

 - macOS Mojave (fully updated)
 - fresh installs of `php` packages from MacPorts

 The problem went away when I re-installed everything using the +debug
 variant, and I'm not sure why.
