  • Grammar: aql
  • Input: for.aql
  • Target: PHP 8.1.12.
  • Driver: You can use "trgen -t PHP" to generate a driver program for your OS. Then, from the command line "php -d memory_limit=4G Test.php -file ../examples/for.aql".
  • Behavior: The parser terminates with out of memory exception. All other examples parse under a second. This is the only example that does not parse, which likely means a significant bug in the runtime.
  • Additional information: #1228 - ArangoDb - grammar and tests grammars-v4#2963 (comment)

Closing this here since the bug is documented over in the PHP runtime code here.
