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'
generated opcodes with 'php':
line # op fetch ext operands

6 ECHO $108
10 7 RETURN 1
generated opcodes with 'php -e':

2 0 EXT_STMT
1 ZEND_DECLARE_CLASS null,
'%00dbhelper%2Fdat%2Fdev%2Fphp%2Fxdebug%2Ftests%2Ftest9.php2', 'dbhelper'
6 2 ZEND_VERIFY_ABSTRACT_CLASS null,
8 3 EXT_STMT
4 ZEND_FETCH_CLASS null, , 'dbhelper'
5 FETCH_CONSTANT ~72, null
6 ZEND_INIT_STATIC_METHOD_CALL
7 SEND_VAL 'tests'
8 DO_FCALL_BY_NAME 1 $108, , -1
9 EXT_FCALL_END
10 ECHO $108
10 11 EXT_STMT
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
