14:57 | Make sure all memory allocations are 8-byte aligned. Ticket #3040. Note that the mem3.c memory allocator returns 4-byte aligned memory allocations. But as mem3.c is intended for use in 32-bit embedded systems, we are not going to change that. (CVS 4978) (check-in: d11e8e307a user: drh tags: trunk) | |
