Bug description: Signal parameter to handler is other-typed (non-integer)
Description:
------------
There is a problem with the type of the parameter sent to a
signal-handling function.
If everytime the signal-handler adds the signal to an array, all array
keys and values will become corrupted. The total number of array elements
will be correct, but the actual values will sporadically become arrays,
etc...
This happens whereever the signal parameter was used. If the parameter is
typecast to an integer, it works perfectly. This happens when the handler
is both a function and a method.
Reproduce code:
---------------
<?php
print("pid= " . posix_getpid() . "\n");
declare(ticks=1);
$arrtemp = array();
function handler($nsig)
{
global $arrtemp;
$arrtemp[] = $nsig;
print("Signal caught and registered.\n");
var_dump($arrtemp);
}
pcntl_signal(SIGTERM, 'handler');
$n = 15;
while($n)
{
sleep(1);
$n--;
}
print("terminated.\n\n");
var_dump($arrtemp);
?>
Expected result:
----------------
As the process receives SIGTERMs from the commandline, the handler adds
each signal value to the global array. When the program terminates, the
list is dumped, and should contain a list containing the correct number of
integers depicting the signals that were sent. The keys are normal indexes.
Actual result:
--------------
A list of the correct number of elements exists, however the actual values
become something else when dumped at program termination.
