Cool, so at least that's confirmed. Can you please attach a debugger to
your php (or run php straight from it). Also, the stack trace is the
result of 'backtrace' command in gdb, not strace (which is a system call
tracer).

$ gdb $(which php)
(gdb) run test.php
(gbd) backtrace

And while you're at it:
$ valgrind --leak-check=full $(which php) test.php

Thank you.
