#40768 [NEW]: nested foreach break -- infinite loop - serious

[rave235 at gmail dot com]

From: rave235 at gmail dot com
Operating system: winxp
PHP version: 5.2.1
PHP Bug Type: Scripting Engine problem
Bug description: nested foreach break -- infinite loop - serious

Description:
------------
i use just build i downloaded from site (5.2.1) no exts, no optimizers.
it seem the $a,$b keep same internal pointer, this is quite serious error
cos $b=$a should create separate array copy and it does but without the
inner pointer.
if you replace $b=$a with $b=array(1,2,3); it works as expected

this was reported and ignored by someone on solaris before as well--
#40608


Reproduce code:
---------------
$a=array(1,2,3);
$b=$a;

foreach($a as $A)
{
foreach($b as $B)
{
echo "$A,$B\n";
break;
}
}

Expected result:
----------------
1,1
2,1
3,1

Actual result:
--------------
1,1
2,1
3,1
2,1
3,1
2,1
3,1
--infinite-
