Hi Ralf, All public distros use avr-libc instead of newlib to build an AVR toolchain: <http://savannah.nongnu.org/projects/avr-libc> AFAIK, it is only RTEMS that attempts to use newlib. And because of this the only testing that is done is when you do it, so I'm not surprised that newlib is broken for the avr. Eric -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31786
