Still fails with r169851. 
Both Linux/x86 and arm-none-eabi versions are OK. Seem it is mingw32 (maybe
also cygwin ?) only.

mingw32-gcc -c -O2 test.cpp                          --  ICE
mingw32-gcc -c -O2 -fno-exceptions test.cpp          --  OK
mingw32-gcc -c -O2 -fno-partial-inlining test.cpp    --  OK
