I've seen NaT consumption faults with an ISV application in a loop
involving speculative loads, too. It was very hard to trace back (occured
at different simulation times in a huge case) and disappeared after we
rewrote the loop and used the latest Intel Fortran compiler. It occured
with both B3 and C0 CPUs under 2.4.7 and 2.4.17. I don't have a testcase
for this, sorry.
Regards,
Erich
