One of my laptops is running Windows 7-64 bits. I'll check tonight and send you my comments.

> ChucK is, at last, 64-bit compatible.
> Lack of native 64-bit support has been a long standing issue with ChucK, 
> and many people in our community over the last few years have contributed 
> to making this happen.  They include Kassen for his ever helpful voice of 
> reason, Paul Brossier (who did a 64-bit port of ChucK to ubuntu, a 
> port that this release is largely based upon), Stephen Sinclair, who also 
> provided a comprehensive and well-executed 64-bit port, and more recently 
> Robin Haberkorn, who has jumped into the ChucKian development fire, as 
> well as Michael Wilson -- your initiative and insights have definitely 
> helped to make this happen.  There have been many helpful discussions on 
> chuck-users and chuck-dev, at CCRMA, as well as much encouragement and 
> support from friends and colleagues like Fernando Lopez-Lezcano.  ... Of 
> course, had we/I architected the VM instructions to not make integer, 
> float, and pointer size assumptions in the first place in 2006 with ChucK 
> 1.2, it would have made things quite a bit easier for everyone.  Yeah... 
> Oops.
> This is the very first release of ChucK that natively support 64-bit as 
> well as 32-bit.  There are a few additional features (and likely a few 
> new, uh, "features").  I imagine a few hot-fixin' rapid incremental 
> releases might be needed.  We have tried to test this thoroughly, in 
> particular on Linux and Mac OS X, and less so on windows.  To be totally 
> honest, we have not been able to even test compilation for 64-bit on 
> windows - if someone out there with access to 64-bit windows (XP or 
> Windows7) who can give this a shot, that would be much appreciated!  In 
> general, users of all supported systems, please let us know if/how well 
> this works for you!
> Part 2 -- on the way!
> Not unlike the final installment of the Harry Potter movies, or perhaps 
> the video game ->Final<- Fantasy XIII (there is a FF XIII-2 and what is 
> effectively FF XIII-3 was just announced), this release will take 
> place in multiple parts, mostly because Spencer is traveling to ICMC in 
> Ljubljana, Slovenia, where he will present our paper on Chugins, Chugens, 
> and Chubgraphs.  Also, there is a little bit more work to do for 64-bit 
> miniAudicle, so that's going to come in CK, part 2, and probably 
> from Slovenia (it seems only fitting to release ChucK from the 
> international computer music conference).  Also, our dear friend Graham 
> Coleman has asked about a chuck-1.3 version of (gasp) Audicle, so there 
> might be a, part 2, b.
> As usual, please see the release notes at the end of this email. Thanks 
> and Happy ChucKin, UpChucKin, Chugin'!  gg!!  ChucK on!!

>    - (added) 64-bit support for all platforms (OS X, Linux, Windows)
>              many thanks to Paul Brossier, Stephen Sinclair,
>              Robin Haberkorn, Michael Wilson, Kassen, and
>              Fernando Lopez-Lezcano, and all of chuck-users!
>    - (added) Math.random(), random2(), randomf(), random2f(), srandom(),
>              and Math.RANDOM_MAX;  NOTE: randomf() returns range 0.0 to 1.0
>              these use the much better random() stdlib functions
>              the existing Std.rand*() and Std.srand() is still
>              be available for compatibility (these to be deprecated
>              in the future; please start using Math.random*())
>              * (NOTE: on windows, Math.random() still uses the same
>                generator as Std.rand() -- we hope to improve this in
>                a future version!)
>              * (NOTE: also see removed below)
>    - (added) chuck --version | chuck --about now print architecture
>              (32-bit or 64-bit)
>    - (added) Machine.intsize() will return int width in bits
>              (e.g., 32 or 64)
>    - (added) examples/array/array_mmixed.ck to verify mixed-index
>              fix (see below), based on Robin Haberkorn's test code
>    - (fixed) multi-dimensional arrays now correctly support mix-typed
>              indices (e.g., strings & ints) (thanks Robin Haberkorn)
>    - (fixed) constants in Math library now cleaner, they include:
>              * Math.PI
>              * Math.TWO_PI
>              * Math.e or Math.E
>              * Math.i or Math.I or Math.j or Math.J // as 'complex' type
>              * Math.INFINITY
>              * Math.RANDOM_MAX
>              * Math.INT_MAX // currently, differs on 32-bit and 64-bit
>              * Math.FLOAT_MAX
>              * Math.FLOAT_MIN_MAG // minimum positive float value
>    - (fixed) Chubgraph.gain(), .last(), and .op()
>    - (fixed) error message printing system for variable arguments
>    - (fixed) StifKarp.sustain now works properly
>    - (fixed) all examples now use Math.random*() instead of Std.rand*()
>    - (removed) Math.rand*() removed --> please use Math.random*();
>              (see 'added' above; Std.rand*() still there, but to be
>              deprecated; please use Math.random*() moving forward)
