Hi Jan, Thank you for report and tracking it down to particular commit. Unfortunately, I can't imagine what is wrong just analyzing the code. I suspect, that something must be wrong with optimization of some particular instruction. Anyway, I need to reproduce the problem Does PHP crashes on a first request to homepage of fresh Drupal 7 installation? If it depends on your data, I can't reproduce it. I know, debugging on Windows is a pain :( I would very appreciate, if you provide more or less compact reproducable case. Thanks. Dmitry.
