Comment (by TheDigitalOrchard):

 It prints my local hostname.

 {{{
 #define PHP_UNAME "Darwin Teds-MacBook-Air.local 18.7.0 Darwin Kernel

 }}}

 I'm running the +debug variant, but nothing special beyond that.

 Still getting random out-of-memory crashing today. Continuing to
 investigate and establish a pattern.

 Heres the latest Fatal error:
 {{{
 Fatal error: Allowed memory size of 134217728 bytes exhausted at
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_php/php73-fpm/work/php-7.3.11/main/output.c:899
 (tried to allocate 880672 bytes) in
 /Library/WebServer/lib/xAppOS/CI_libraries/xAppCI_Output.php on line 173
 }}}

 I'm unclear on *why* this started happening. It only happens on pages that
 involve decrypting a lot of records using OpenSSL.

 I'll update when I know more.
