Looks like an ARM error.
ARM error? Sorry, what's an/the ARM? Really, anyone run into something like this before? I'm completely stumped..
-jim lee
Without any context, we're pretty stumped too.
what's an/the ARM?
Sadly I don't have any context to give! I was coding along, minding my own business, did a little change. Moved a couple local variable to being global.. Then I got this error. So I quicly move them back and I still get the error.
Here's the library I was working on..

Sketch?
Sadly I don't have any context to give!
IDE?
What version of avr-gcc are you using? There is a suggestion here that this is fixed in a later version:
http://lists.gnu.org/archive/html/avr-gcc-list/2008-05/msg00163.html
IDE? Its the Arduino 1.0 IDE. Where do I look for the other context bits?
-jim lee
You can go ahead and post /var/folders/QT/QToGN6mK2RmPDU+1YrkbM++++TM/-Tmp-//ccbinRWR.s too. Save it to pastebin if it's too large for the forum.
Oh, and it looks like you are running Linux? Open a command prompt and run "avr-gcc -v". And while you're at it, "avr-as -v". This will tell us which tools you're using. Also, which version of which distro are you running?
Ok..
I'm running an old Mac here not really Linux. After a bunch of poking around with google etc. I got some clues to what people were seeing this error over and from that I was able to locate where it was being generated in my code, but I still don't know why its upset..
void colorObj::setColor(word color16) {
word redMask = (B11111000 * 256);
//word greenMask = (B00000111 * 256) + B11100000;
//word blueMask = B00011111;
red = (color16 & redMask) >> 8;
//green = (color16 & greenMask) >> 5;
// blue = color16 & blueMask;
//Serial.print("color16 : ");Serial.println(color16,BIN);
//printRGB();
}
Seems its the line : red = (color16 & redMask) >> 8;
And there's a bug in the compiler? Doesn't the compiler come packaged in the IDE? How do I find the version of my compiler on a Mac?
Thanks!

Open a Console window. Type "avr-gcc --version", eg.
$ avr-gcc --version
avr-gcc (GCC) 4.3.3

-bash: avr-gcc: command not found
You have me totally confused. The terminal on my Mac? Witch makes no sense to me 'cause I don't think I have any compilers there. Or, is there some sort of console window on the IDE that I don't know about. I'm assuming there's a complier in there.
-jim lee
How old is your Mac? Use Spotlight. Type "terminal". Accept the Terminal program. You will get a command-line prompt. You can type stuff there.
Find Arduino in your Applications folder. RH click and select Show Package Contents. Now search for avg-gcc.
Drag the resulting file into the terminal window, and append --version, eg.
/Applications/Arduino.app/Contents/Resources/Java/hardware/tools/avr/bin/avr-gcc --version
Hmm I got the same error, using Arduino IDE v1.0.1 on OSX:
Thats the line
g=(g*mulCol + g2*oppositeColor) >> 8
The error is a asm error when using the movw instruction... The funny thing is, I use this code in another project without a problem, I reuse this piece of code and this bug hit me... any hints?
Used Version:
bash-3.2$ /Applications/Arduino.app/Contents/Resources/Java/hardware/tools/avr/bin/avr-g++ --version

pff I just found the solution seconds after this post
g was declared like this:
unsigned int g;
and I guess this addition will overflow the unsigned int:
g=(g*mulCol + g2*oppositeColor) >> 8
I fixed it with:
g=((g*mulCol)>>8) + ((g2*oppositeColor)>>8);
However I have NO clue why it works in my previous project (ExpeditInvaders/ColorSet.ino at master · neophob/ExpeditInvaders · GitHub)...
