Thanks Carl.
Intel say the first 2 are 'mostly complete' but not released.

They ask if you could file a bug for the ALS bug.

Thilo thinks its O3 related.
As a work around, I'd suggest an ifdef and
#*pragma optimize* ( "", off )
around the code you suspect.  That would also help Intel track down the bug.
