I guess that member function is virtual? G++ always gives this warning for
every virtual member function. It must have something to do with the vtable.
Probably a bug in avr-g++. The warning should be harmless, since avr as an
8 bit architecture obviously doesn't have any alingment requirements.
That was my thinking too - virtual functions causing compiler
confusion. I refactored one class a few months ago, just to clean it
up (still has virtuals), and it went away, but now I see it in a new
class. These things make me uneasy. The class was full of
pure-virtuals, that were all implemented in a derived class, and it
just wouldn't link to save my life. I stubbed all the pure's into do
nothing functions, and it links fine, and calls the derived functions
correctly from a pointer to the base. I double-and triple checked the
signatures, and they were identical. I guess avr-g++ just doesn't
handle pure virtuals? The alignment warning is still there, however.
I guess I'll just mask it out. As you said, it appears harmless.
