Comment (by guest):
Thank you for looking into this issue!
The example works with Darcs-HEAD of
http://code.haskell.org/storablevector/
This version is named 0.2.5.
I may also tag and upload this version to Hackage in order to make the
problem reproducable in future.
The StorableVector construction using mainChunky0Builder is also three
times slower than its counterpart mainChunky0 and I have no idea why.
Maybe I should file a separate ticket for that,
but I'm uncertain whether this is my fault or GHC's.
Btw. don't miss to listen to the 40 MB of cool sound that those functions
generate using
play -r 44100 speed.f32
(play is part of the SoX project)
:-)
