After looking at the generated trees, I noticed that it isn't actually
the integer conversion, but rather the widening multiply optimization
that is broken. I then started poking at gcc and its awful use of svn,
and managed to identify the commit that fixes it; manually applying it
to 4.7.3 fixes it there to.

The appropriate bug report is
<http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54295>. I'll backport the
fix to 4.6 and 4.7.
