Description Tuomas Pennanen 2008-09-14 20:57:46 UTC 
Since revision 139590 (including) GCC fails to build successfully. Revision 139589 can be built successfully with the same configuration.


Configuration:

../trunk/configure --prefix=/usr/local/avr --target=avr --enable-languages=c,c++ --disable-nls --disable-libssp --with-dwarf2


Output when running "make":

Anatoly Sokolov committed a patch as revision 140360 that may (or may not) fix this problem. See his post on the patches list:
http://gcc.gnu.org/ml/gcc-patches/2008-09/msg01054.html

Please try a more recent version to see if this patch solves this problem.

Thanks.
Comment 2 Tuomas Pennanen 2008-09-15 12:49:29 UTC 
Yes, I just built revision 140370 successfully.

I just had had to initially wait three more hours before checking out HEAD...
Comment 3 Eric Weddington 2008-09-15 13:13:14 UTC 
Marking bug as fixed.
