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

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

Works for me. Please also try a snapshot.

We had a similar problem and found that disabling x-debug fixed it.  I don't know if you had it installed, but it is worth a try.
