I can confirm that this bug is present for GCC 4.8 dated 20121221, which is
available here:
http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/rubenvb/gcc-4.8-unstable/i686-w64-mingw32-gcc-4.8-unstable-win32_rubenvb.7z/download

I get:

lto1.exe: internal compiler error: cannot read LTO decls from
