-------------------------------------+--------------------------------------
As far as I can tell, PMC attribute blocks are not aligned as they are
allocated in fixed-size PMC attribute pools. The memory manager assures
that an attribute block is at least the size of a pointer, since free
attribute blocks will be linked on the free lists. But it does not assure
that each block starts on a pointer-aligned boundary. This probably
doesn't matter to the standard PMCs, since their attributes are all
integers, floats, or pointers. But a custom PMC could have, say, 13 bytes
of short integers and/or characters.
I'm not completely sure I've analyzed this correctly, so I'll assign this
ticket to myself for further analysis.
