>BTW I do not see (beside obfuscation) the interest of the constructs:
It is the construct:
jt=t(j2)
tt=tt+tt
t(j2)=jt
that is being optmized away or done incorrectly when the second matrix stays
the same. The obfuscation is required because the program is doing virtual
memory management and at this point floating point data is in one of the raw
integer virtual arrays and so that is the game that is played to do the
floating point add.
