compiler segfault:

Build instructions:
Clone the PHP engine: https://github.com/php/php-src
./buildconf
./configure -C CFLAGS="-DPROFITABILITY_CHECKS=0 -DZEND_RC_DEBUG=1
-DZEND_VERIFY_FUNC_INFO=1 -fanalyzer" --disable-all --enable-debug
--enable-opcache --enable-zend-test --enable-address-sanitizer
--enable-undefined-sanitizer
make
I would imagine that not all of the configure flags will produce the error but
that's the build I've run
