Can this happen ?
More to the point, if a meta-object does contain sub-objects with their own
symbols, shouldn't the offsets of those sub-objects be computed by calculating
the difference between the symbol's address and the meta-object's start
address. Rather than just by being pre-calculated to some fixed value ?
If it is possible however then maybe the message should be:
warning: alignment 32 of symbol `com2_' in test2.o changed to 64 to match
test1.o
warning: beware: this might break code that relies upon the alignment being
32.
