Bug description:Stack overflow makes PHP crash with Segmentation Fault
Description:
------------
Whenever a PHP script encounters a stack overflow, it just dies with a
message to
stderr stating: "Segmentation fault".
Test script:
---------------
#!/usr/local/bin/php
<?php
function segmentationFaultFunction()
{
static $counter;
echo ++$counter . ' ';
$func = function(){
return segmentationFaultFunction();
};
$func->__invoke();
return $func;
}
$function = segmentationFaultFunction();
$function->__invoke();
echo 'Done, no segmentation faults' . PHP_EOL;
Expected result:
----------------
I expected my error handler to be called with a stack trace.
The best solution would be if PHP registers the error before crashing and
throws
an exception with the stack trace.
The second best solution would be if PHP could give us a better error
description
than Segmentation fault. Maybe just terminate the script with an error that
looks
like this: "Stack overflow in file: /scripts/test.segfault.php on line 10".
Actual result:
--------------
Script terminates with an uncatchable error to stdout: "Segmentation
fault".
