## #476 — Derick Rethans — 2003-03-29T20:38:30+00:00

Hello,


I encountered a weird bug that I cant quite figure out. It has to do 
with the extended-info mode (-m) of PHP.


problem:
the opcodes generated in extended-info mode are incorrect


testscript:
<?php
class dbhelper {
  function quote($s) {
    return addslashes ($s);
  }
}

echo dbhelper::quote("tests");
?>


php configure:
./configure --disable-all


output with 'php testscript.php':
tests


output with 'php -e testscript.php':
<br />
<b>Fatal error</b>:  Undefined class constant 'quote' in <b>/dat/dev/php/tests/testscript.php</b> on line <b>8</b><br />
/dat/dev/php/tests/testscript.php(8) : Fatal error - Undefined class constant 'quote'

        12  RETURN                                           1



As you can see there is no EXT_FCALL_BEGIN, and there is a
FETCH_CONSTANT added (which causes the error message).

I've no clue why, Andrei can not reproduce it, Timm can.

regards,
Derick
