Traced down to optimize-strlen GCC optimization (part of -O2).
does not work: -O2
works: -O2 -fno-optimize-strlen

Did some digging using php-7.3.0beta1 tag and provided PHPUnit repro script in OP.
Compiling PHP with gcc-8 as such:
git clean -xdf && ./buildconf --force && ./configure CC=gcc-8 CFLAGS=XXX &&
make -j 12
With various GCC optimization levels, the results are:
gcc-8 with -O0 works
gcc-8 with -O1 works
gcc-8 with -O2 does not work
gcc-8 with -O3 does not work
gcc-8 with -Og works
gcc-8 with -Os works
gcc-8 with -Ofast does not compile

Interesting. Any idea what might be different on my system that would cause this? What I find weird
is that you were able to reproduce the issue initially but now you no longer can while I am still
seeing it.

Did this
git fetch --prune
git reset --hard
git clean -xdf
git checkout master
git rebase origin/master
./buildconf --force
./configure --prefix=/tmp/PHP --disable-cgi --enable-opcache --enable-opcache-file --with-zlib
--with-xsl=/usr --enable-mbstring --enable-bcmath --with-gmp --with-openssl --with-bz2 --enable-soap
--enable-intl --enable-pcntl --with-tidy --with-curl --enable-zip --with-readline --without-pear
