ICE occurs not only rx-elf but also sh-elf, m32c-elf, h8300-elf. No error in
x86_64-linux-gnu.

no problem if -fno-lto or -gstabs.

This problem appears since r173860 (PR lto/48207).

The fault also happens natively:

cbuild@ursa2:~$ g++ -flto -std=c++0x -g -xc++ /dev/null -include functional

This isn't FSF 4.6.3 but is pretty close.

The 4.6 branch has been closed, does this problem exists also in 4.7.3 or
later?
