Ok, I've finally found were this strange bug come from !!

This strange bug appears only when we compile oaf with gcc 2.96 and "-O3
-fomit-frame-pointer -pipe -mcpu=pentiumpro -march=i586 -ffast-math
-fno-strength-reduce" :((

This bug doesn't appears with egcs nor gcc 3.0.. I've given this problem
to our Mdk gcc specialist :))
