Bug description:Eval triggers segmentation fault when argument is a string returned by sprintf

Description:
------------
eval(), when provided with a parameter string returned by the sprintf()
function, 
causes the PHP script (in console at least) to crash with a segmentation
fault.

Test script:
---------------
// Crashes
eval(sprintf('class Roger {}'));

// Does not crash
eval('class Roger {}');

Expected result:
----------------
No segfaulting.

Actual result:
--------------
Segmentation fault
