Comment (by eriktorbjorn):

 It looks to me like it allocates memory blocks (in expr.cpp) for one or
 more `Expression`s, plus one byte at the beginning to store the size of
 the block, measured in number of `Expression`s.

 It's probably that that puts each `Expression` on an unaligned address.

 I'm not really familiar with this engine, but it seems to me that there
 could be two ways forward:

 - Instead of using a single byte, use a larger type so that the
 `Expression`s end up on aligned addresses. Is there any good way to figure
 out what the alignment is?
 - Instead of storing the size in the memory block, wouldn't it be possible
 to ask the memory manager for the size with `globalSize() /
 sizeof(Expression)`?
