Hello

I have an issue on a particular virtual machine.

Segmentation fault (core dumped)

The related code : 

$value = $object->getConfigYml(); //retrieve some string
file_put_contents("/tmp/debug", $value);
$value = file_get_contents("/tmp/debug");
bsLogger::debug('getConfigYmlObject 13.1');//write some debug to a file
$var = json_decode($value, true);//This line is crashing according to trace
bsLogger::debug('getConfigYmlObject 13.1.1');//not reached when crash

The json string is valid.
If I try, outside my execution code to json_decode it, it's working well : 
cat test.php                                                                                          <?php
$cnt = file_get_contents("/tmp/debug");
$ar = json_decode($cnt, true);
var_dump($ar);



If I reboot my virtual machine, i d'ont have any issue, the problem come after some time (some hours)
