After some intense debugging, I found the problem. One
block in the file triggered a very rare bug in the LPC
coefficient quantizer caused by insufficient floating
point precision. There is a snippet to compute the
log(base 2) of a number:

This appears to be triggered by -ffast-math.

Three Identical systems - short cut to setting up the drives?
I am building three identical systems. Well they will have different
host names, and with time the software setups will drift. But at
install time they are identical.
Is there some way, (with dd I might guess) to do a hardare level copy?
All three drives are Hitachi DK23DA-40F (40Gb). Supposedly factory
reconditioned (they are in sealed bags with a drive sticker stating:
"Refurbished to Hitachi Global Storage Technologies Specifications").
I would want to copy the paritition table and my 3 partitions (/boot,
swap, LVM (/ and /home ext3 partitions in the LV...
