Building gcc 3.3 branch for v850-elf with --disable-multibs --enable-
languages=c++ in a combined tree with cvs binutils and newlib, I get:

/tmp/mainline/obj/v850-elf/v850/libstdc++-v3/include/bits/istream.tcc: In
   function `std::basic_istream<_CharT, _Traits>&
   std::getline(std::basic_istream<_CharT, _Traits>&, std::basic_string<
_CharT,
   _Traits, _Alloc>&, _CharT) [with _CharT = char, _Traits =
   std::char_traits<char>, _Alloc = std::allocator<char>]':

make[6]: *** [misc-inst.lo] Error 1

Changing CXXFLAGS to -O1 cures the ICE.
