FFI::new interacts badly with observers

[derickr]

Description

If you compile PHP with:

./configure --enable-debug --disable-all --enable-zend-test --with-ffi
make clean && make

And then run:

sapi/cli/php -n  -dzend_test.observer.enabled=1 -dzend_test.observer.observe_all=1 /tmp/ffi-test.php

Where /tmp/ffi-test.php is:

<?php
$ffi = FFI::cdef("", "libc.so.6");
$ffi->new("int");

Resulted in this output:

…
Fatal error: Uncaught FFI\ParserException: unexpected '<EOF>' at line 1 in /tmp/ffi.php:3
Stack trace:
#0 /tmp/ffi.php(3): FFI->new('')
#1 {main}
  thrown in /tmp/ffi.php on line 3

But I expected it to not have an exception.

Without the observer enabled, this also does not show an exception.

This is basically #11548 but for FFI.
I have a local patch that works and I'll PR it soon.

Thanks for creating this Issue from xdebug one.

Please, note that this issue affects 8.2 and 8.3, so backports are needed

The PR is created against the 8.2 branch and will be merged upwards, so it will be applied to 8.2 and 8.3 🙂
