Version 4.3.0 of AVR GCC has known code generation problems that were fixed with patches in WinAVR. My guess is that the Ubuntu distro of AVR GCC is not built with these patches. You need to either build AVR GCC with those patches, or use version 4.3.2 where these code gen bugs are fixed. _______________________________________________ AVR-GCC-list mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/avr-gcc-list
