I would like to check if the JIT provides an improvement for PHP-Parser.
Unfortunately I'm getting a segfault when running the tests. Should be
reproducible with
git clone git@github.com:nikic/PHP-Parser.git
cd PHP-Parser
composer install
php-jit vendor/bin/phpunit
I tried to debug this. Unfortunately my gdb doesn't seem to work with JIT:
It hangs when the script starts running, on line Zend/zend_gdb.c:84 in
zend_gdb_register_code. I don't know if that's a bug or I need to do
something additional here (I'm using GNU gdb (Ubuntu 8.1-0ubuntu3)
8.1.0.20180409-git).
