------- Comment #10 from ah dot linder at arcor dot de 2010-08-19 22:23 ------- Created an attachment (id=21525) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=21525&action=view) preprocessor output for augi.cpp
I have the same problem on Fedora 13, avr-gcc-c++-4.5.1-1.fc13.x86_64 avr-gcc-4.5.1-1.fc13.x86_64 avr-binutils-2.20-2.fc13.x86_64 avr-libc-1.6.7-2.fc13.noarch Using built-in specs. COLLECT_GCC=/usr/bin/avr-g++ COLLECT_LTO_WRAPPER=/usr/libexec/gcc/avr/4.5.1/lto-wrapper Target: avr Configured with: ../gcc-4.5.1/configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --target=avr --enable-languages=c,c++ --disable-nls --disable-libssp --with-system-zlib --enable-version-specific-runtime-libs --with-pkgversion='Fedora 4.5.1-1.fc13' --with-bugurl=https://bugzilla.redhat.com/ Thread model: single gcc version 4.5.1 (Fedora 4.5.1-1.fc13) avr-g++ -c -g -w -v -fno-exceptions -mmcu=atmega1280 -DF_CPU=16000000L augi.cpp -oaugi.cpp.o avr-g++ -g -v -Wall -mmcu=atmega1280 -Wl,-Map,augi.map -o augi.elf augi.cpp.o avr-objcopy -v -j .text -j .data -O ihex augi.elf augi.hex The source file is a simplified version of the arduino sketch of comment#6 (got rid of the arduino specific stuff and the interrupt code), the problem is triggered by the second "Serial" Dummy Object. With avr-g++ 4.5.1, I don't get any output, with avr-gcc-c++-4.3.3-3.fc13.x86_64 & avr-gcc-4.3.3-3.fc13.x86_64 I get a stream of 'A' as expected. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44617
