I am glad there was not more fallout. Unfortunately powerpc-aix was
not so lucky:
/farm/dje/src/src/libstdc++-v3/src/c++98/streambuf.cc: In function
'std::streamsize
std::__copy_streambufs_eof(std::basic_streambuf<_CharT, _Traits>*,
std::basic_streambuf<_CharT, _Traits>*, bool&) [with _CharT = wchar_t;
_Traits = std::char_traits<wchar_t>; std::streamsize = long int]':
/farm/dje/src/src/libstdc++-v3/src/c++98/streambuf.cc:113:5: internal
compiler error: in get_loop_body, at cfgloop.c:831
Line 831 is:
gcc_assert (tv == loop->num_nodes);
Reverting the patch fixes the ICE.
