Uncatchable fatal error: Multiple final modifiers are not allowed (emitted by parse_code())

[TysonAndre]

php > try { $x = ast\parse_code('<?php class C { final final function foo($fff) {}}', 50); } catch (\Throwable $e) {print("Caught exception\n"); echo $e; }

Fatal error: Multiple final modifiers are not allowed in string code on line 1

This was observed in php 7.1.

Is there any way to make this into a catchable \Error?
The fact that it's uncatchable may affect some applications

(Noticed when running this extension on the test phpt files in php-src)

Similar issues noticed:

halt03.php (__HALT_COMPILER must be in top level)
errmsg_010.php
declare_003.php declare_002.php Fatal error: Encoding must be a literal

Yeah, we should either change these into exceptions or, if possible, try to generate them during compilation. This will require some larger upstream changes though, so in the best case only for 7.2.

Filed https://bugs.php.net/bug.php?id=75218 to track this (Didn't see anything similar in php.net when I checked)

I'm closing this in favor of the upstream report.

This has been fixed in PHP and I've added a test to verify the fix for php-ast in 60acf78.
