I guess I catched.
There is likely an optimization bomb that never exploded before during
For what ever reason gcc-4.3.4-4 activates it and all the previous version not.
slamch.f and dlamch.f could fall in never ending loop if the
optimization is active.
The funny thing is that they were created in such a way to fool
optimization to recover hardware real data.
So at the end it is a PEBCAK problem from the first time that I
adopted lapack and used automake/autoconf.
