PHP Bug Type: Reproducible crash
Bug description: array_map with NULL callback causes crash
When used with NULL as the callback function, array_map
causes a SIGBUS.
Example: this crashes
<?php
$a=array(1,2,3,4);
$b=array('a','b','c','d');
$c=array_map(NULL,$a,$b);
print_r(
$c);
?>
But this works:
<?php
function foo($x,$y)
{
return array($x,$y);
}
$
a=ar
r
a
y(1,2,
3,4);
$
b=array('a','b','c',
'd
');
$c=array_map('foo
',
$a,$b);
print_r($c)
;
?>
