            Status: UNCONFIRMED

See <file:///usr/share/doc/gcc-4.9/README.Bugs> for instructions.
Preprocessed source stored into /tmp/ccSYvoB9.out file, please attach this to
your bugreport.



I believe this is a regression because g++4.8.2-19ubuntu1 compiles the same
code which executes as expected.

System details:

$ g++ --version ; echo ; uname -a ; echo ; cat /etc/lsb-release
