bug#20308: Problem building emacs trunk on Fedora 21 x86_64

Hmm, I regularly build the GNU Emacs master on Fedora 21 x86-64, and I don't run 
into the problem.  What happens if you build as follows?  Get a fresh checkout 
from the master, and then run:

./autogen.sh
./configure CFLAGS='-g3 -O0'
make

If this doesn't work for you, please email us what it outputs.  If it crashes 
the same way as before, please do this:

cd src
gdb temacs
(gdb) run --batch --load loadup bootstrap
(gdb) backtrace
