New issue 1564 by [email protected]: src/deoptimizer.cc:1465: warning: dereferencing type-punned pointer will break strict-aliasing rules
http://code.google.com/p/v8/issues/detail?id=1564

r8556 introduced a change that makes the build fail with gcc 4.2.1 on i386 freebsd.

  v->VisitPointer(reinterpret_cast<Object**>(&function_));

Raises a warning (and stops the build since -Werror is in effect):

src/deoptimizer.cc:1465: warning: dereferencing type-punned pointer will break strict-aliasing rules

Output of `gcc -v`:

  Using built-in specs.
  Target: i386-undermydesk-freebsd
  Configured with: FreeBSD/i386 system compiler
  Thread model: posix
  gcc version 4.2.1 20070719  [FreeBSD]

Tested with the current bleeding edge (r8666).
