Possible overflow of _candidate_bits in stream_encoder.c
...Kind regards, Martijn van Beurden
P.S.: I'm sending this for the second time, sorry if it arrives twice.
It seems to me e-mails over 50kb don't get through.

Possible overflow of _candidate_bits in stream_encoder.c
Recently I was trying some new approaches to improve FLAC compression, when
I stumbled on a possible overflow. The reason this has not come up earlier
is because the encoder only hits this point when the estimate of the
rice_parameter is very much off.
To trigger this overflow, one has to force rice_parameter to 0 in for
example the function evaluate_lpc_subframe in libFLAC/stream_encoder.c.

group by + sum
Hi.. I need some support...
table:
week_id, user_id, project_id, hours
ex. =>
33, 2, 1, 10
34, 2,1,15
33, 2, 2, 20
35, 3, 1,20
etc.
Want to display a sum of hours per week_id per user_id
I have:
@hours = HourUser.includes(:user).group_by { |h| h.week_id }
@hours.keys.sort.each do |hour|
@hours[hour].collect(&:stunden).sum
Hours are summed up, but not sorted by user_id..
