with a non-debug build; we'd get:

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 140044069608296 bytes) in Unknown on line 0

and:

I couldn't reproduce that issue at the command line nor via 3v4l.org

http://3v4l.org/Sqbeg

Are there any further environment specific things one needs to respect to reproduce?

Could this depend on php-fpm somehow? That seems to be 100% broken here

Also; please tail your error-log while testing this; I have confirmed the messages on 2 machines (1 of them it also outputs the exception, but also the exhausted message in the error-log)

I reproduced this error with php5.6.0 and php5.6.5.
The bug occures only if html_errors is set to true, and the exception is displayed (not catched).

Test script (encoded in iso-8859-1) :
   ini_set('html_errors', true);
   throw new Exception('société');

 [2015-02-22 01:34 UTC] rasmus@php.net

I still can't reproduce this.

I have this script:

   <?php
   ini_set('html_errors', true);
   throw new Exception('société');

I have converted it to iso-8859-1:

$ file test.php
test.php: PHP script, ISO-8859 text

$ php test.php
<br />
<b>Fatal error</b>:   in <b>/test/test.php</b> on line <b>3</b><br />

It is also clean in Valgrind. Can you reproduce this in current releases of PHP 5.5 or 5.6 from the command line?

@samuel_carriere; are you also using fpm? I could never reproduce this through the cli, but fpm was pretty consistent.

Even with the html-error set, it won't crash on 3v4l either (through cli): http://3v4l.org/fgplv

The same error still occurs in PHP 5.6.29-0+deb8u1 (running as mod_php on Apache 2.4.10).

Test script:
-----
<?php
throw new Exception('täst');
-----

With html_errors set to On this produces a segfault with:

[Fri Jan 27 13:38:10.259970 2017] [core:notice] [pid 6] AH00052: child pid 29 exit signal Segmentation fault (11)

Setting html_errors to Off does not produce a segfault but an expected error:

[Fri Jan 27 13:38:46.035301 2017] [:error] [pid 30] [client x.x.x.x:43227] PHP Fatal error:  Uncaught exception 'Exception' with message 't\xe4st' in /var/www/html/test.php:3\nStack trace:\n#0 {main}\n  thrown in /var/www/html/test.php on line 3

Note that this bug will therefore not occur when being run on CLI as the value for html_errors is hardcoded to Off there.

Also note that it does not matter if the Exception is caught in a surrounding try-catch block or not.
