Subject: [boost] bjam assertion failure: does it really need stack alignment?

Hi,
A question for the bjam maintainers about
https://svn.boost.org/trac/boost/ticket/8993
The file tools/build/v2/engine/function.c contains this check:
static void check_alignment( STACK * s )
{
assert( (size_t)s->data % sizeof( LIST * ) == 0 );
}
However, things other than LIST* are allocated on the stack. For example
expand_modifiers() allocates VAR_EDITS objects, whose size turns out not to be
a multiple of sizeof(LIST*) on some architectures (m68k in the above ticket).
Does check_alignment() still make sense?
Thanks,
-Steve
