Error when compiling simple SPARC ASM math code

Writing SPARC asm code to evaluate a hardcoded statement, but I'm getting an error I don't understand. I've searched all over, and while it seems to come up a lot in some bug reports out there, there's no real clues that I've found for programmers. Yes, it is homework, and yes, I'm not finished, and yes I have branch delays all over the place. I'll get to them on my own, but I need to know what the error is. This error's not telling me anything useful, and the books I have aren't any good for it either.

I'm really new at this, so any help would be greatly appreciated.

then when I try to define the macros and compile I get:

A bug in the assembler causes debugging code to add unaligned data access. Don't use -g but perhaps -gstabs if you need debugging information. There maybe an update for gas that fixes the problem too.
