--- Comment #5 from David Binderman <dcb314 at hotmail dot com> --- Another runtime bug, probably related: ../../trunk.d1/gcc/expmed.cc:3282:26: runtime error: signed integer overflow: -9223372036854775808 - 1 cannot be represented in type 'long int' I am not sure if this one should be a separate bug report or not.
