Hi,
Someone knows, if one day, this bug will be patch officially ? : http://www.techytalk.info/blank-product-page-magento-compilation/
I recently re-discover this bug, it triggers a 500 error without log anything. Issue appear on 1.7.0.2, 1.9.0.1, 1.9.2.4, and certainly more.
The solution is just to replace an include by include_once.
