In the beta version, compilation was moved inside a HANDLE_BLOCK_INTERRUPTIONS/HANDLE_UNBLOCK_INTERRUPTIONS block, so the zend_bailout deferral is no longer safe. For example, a syntax error in the script will result in a partially compiled opcode array to be cached in APC. I don't yet have an alternate solution. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
