@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

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?

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');

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)
