Bug#330595: Miscompilation with -fomit-frame-pointer -O3 -funroll-all-loops

[Camm Maguire <camm@enhanced.com>]

Greetings!

My apologies, but time is quite tight.  I barely found the time to
file the original bug.  The overhead to the bug submitter implied by:

Camm, thanks for the increasing number of bug reports ;-)

- please make sure to test with recent compiler versions (currently
  4.0.1-9).
- please check with optimization levels suggested by policy (-O2)
- please check using gcc-snapshot.

At least I cannot reproduce this with 4.0.1-9.

Thanks, Matthias

is quite high.  Nevertheless, I'll try to get to it.

Take care,
