RE: [avr-gcc-list] Unrecognizable insn

[HutchinsonAndy]

I have been unable to reproduce this on gcc 4.1 and 3.3.3

This might be related to versions so check which winavr/gcc you are using.

The code are I got from 3.3.3 put unused arrays on the stack!! The error 
suggests the unrecognised move is the load of frame pointer - so maybe this got 
fixed sometime.

I have not check definition, but I assume that you wanted array on 
program_memory??
