Well, the problem was my CXXFLAGS, they have the -O3 optimization (i read from
http://www.eldemonio.org/docs/freebsd/optimizar.html), the solution was to
compile jade with this variables to override my make.conf:
NO_CPU_CFLAGS=yes NO_CPU_COPTFLAGS=yes CFLAGS=-O CXXFLAGS=-O
Now everything works fine, thanks ! :-D.
