Hi, There's an update to the Debian package which will be: gcc-avr_4.5.3-4
This version has backported fixes for: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46779 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50289 >From Hakan, the Debian maintainer: "I'm releasing now, it should show up in debian unstable during the day and propagate to testing after 10 days if no issues show up. How/When it'll propagate to ubunu I dont know. This release breaks gcc.c-torture/execute/pr23135.c and gcc.c-torture/execute/simd-1.c from the gcc testsuit. They are both dealing with SIMD-support but supposed to pass even if the target does not have SIMD (they do pass on version 4.5.3-3). But I guess this is a minor issue..." > Hi, > > A warning that this version has the bug as described and fixed by Georg > below.
