### Description
The following code:
```php
<?php
class Test {
public $lib;
public function __construct() {
$this->lib = \FFI::cdef("extern void setCloseSessionCallback(void(*fun)(unsigned long
cid));
extern void testCloseSessionCallback();
", "./libsomelib.so");
}
}
$tclass = new Test();
$tclass->lib->setCloseSessionCallback(function($cid){
echo "ok\n";
});
$tclass->lib->testCloseSessionCallback(); //this function creates new std::thread from c++
stl, sleeps 2 seconds and calls function passed to setCloseSessionCallback
while(true); //prevent php script from completion because testCloseSessionCallback running in other
thread
```
Resulted in this output:
```
segmentation fault (core dumped)
```
But I expected this output instead:
```
ok
```
gdb backtrace:
