True. However, breaking `long long' is a serious regression. If a developer can't trust that, what can they trust?


Historically it hasn't been all that trustable anyway.  I don't have a
testcase handy but CORE_ADDRs in GDB backtraces tend to be wrong, even
when they're properly saved to the stack.  Et cetera.

On the i386. The case that Mark identified.
