gcc-avr (4.6.0-3) and avr-libc (1.7.0-1) incompatibility

I've been away from avr development for a few months...turns out that the current combination of gcc-avr and avr-libc (has been flagged as out of date since 2011-05-30) but has not been working for since gcc-avr was upgraded on 2011-04-22.

The small piece of Teensy code I was compiling successfully, is now crashing the compiler:

make: *** [main.o] Error 1

Now I know the Arch policy of not reporting bugs on out-of-date packages, but the current combination does not work (I'll be reporting a gnu bug shortly, if it already hasn't been done). I may be mistaken, and this could just be a problem with the gcc-avr compiler.

Hmm, looks like it may have been very recently resolved: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48459
