--- Comment #14 from David Binderman <dcb314 at hotmail dot com> --- (In reply to Richard Biener from comment #10) > Didn't check ubsan bootstrap. I did. It seems to work at the -O2 level. -O3 level hasn't worked for months, but that's an old problem. ints and longs not wide enough types. Using a non-gcc compiler, for example clang, at the start seems to break the ubsan bootstrap. Would it be worth me sending in another bug report or just posting it here ?
