The first step is to fill out a bug report at the GCC project. Let me know the bug number so I can track it. Next, it needs to be determined which version caused the biggest problem. 4.2.x? 4.3.x? 4.4.0? Or HEAD/4.5? It could just get progressively worse with each version, or perhaps there is some big jump in code size. _______________________________________________ AVR-GCC-list mailing list AVR-GCC-list@nongnu.org http://lists.nongnu.org/mailman/listinfo/avr-gcc-list
