Comment (by josef):
Using the bounds (minInt,maxInt) was probably the wrong thing todo. My
concern when filing the bug report was not the arithmetic overflow but the
fact that ghci crashes when it tries to allocate a too large an array. It
is still possible to provoke a crash if you change the array bounds to,
say, (2,maxInt). Should I open a new ticket or reopen this one?
