I doubt that (but where would -fstrict-aliasing come from?).

Yes, I doubted it too. "-fstrict-aliasing" is enabled at -O2 (http://gcc.gnu.org/onlinedocs/gcc-4.7.3/gcc/Optimize-Options.html#index-O2-706).

Please try the latest trunk and see if its solves the problem.

Tried r116235 with

'/c/emacs/trunk/configure' --prefix c:/emacs/emacs-116235 --without-png --without-jpeg --without-xpm --without-gif --without-tiff --without-gnutls --without-xml2 --enable-locallisppath=%emacs_dir%/../site-lisp

Seems fixed, many thanks. I should rebuild with the libraries enabled to be sure. I will let you know the result.
