Yes, I do recall that...I described to the (presumably) ARM GCC people
what I was seeing and how it was happening...I don't recall much coming
from that beyond "It doesn't sound like the same bug we're thinking of..."
The optimization bug I was seeing was on an ARM machine used for linux/iPaq
builds (owned by the handhelds.org folks)...I'm pretty sure it's the same
bug everyone is seeing, as I tracked it down on the old Netwinder site at
one time.

I haven't kept up with any of the GCC ARM stuff but I sincerely hope they
track this annoyance down.  I know that as of GCC 3.0 they had not.
