A 32-bit computer can only handle 3 gigs of RAM. That's the big deal with 64-bit computers, they handle a lot more. While your computer is 64-bit and your OS is 64-bit, the build of Pd you are running is 32-bit. That means that your Pd cannot use more than 3 gigs of RAM no matter how much is in the machine.
My guess is that your Pd patch wants to use more than 3gb of RAM, then crashes. Try running Activity Monitor and seeing how much memory 'pd' is using.
I could be wrong that this is the cuase of hte problem tho...

Okay... I'd run across this before when trying to research this issue... Sorry to be so dull-witted about this, but does this mean a physical reduction of my RAM itself from 4 GB to 3 GB? Or am I missing the point and I need to do something else?
Thanks again for looking into this so quickly, I really appreciate it, getting confirmation about all of this is really huge.

So it is not the GUI, but 'pd' itself having the issue: pd(272,0xa03ce720) My guess is that maybe its a 32-bi/64-bit issue. I think that a 32-bit app can only address 3 gigs of RAM. Pd is buildable has 64-bit, but there isn't a release for Mac OS X built as 64-bit yet.

It happens every time without variation... I've tried it on two machines, one is:
MacPro Quad-Core Intel Xeon, 2.93 GHz processor, 4 GB memory, ATI Radeon 4870 (the apple tweaked version, not the ATI version), BlackMagic Intensity Pro video card... and it's mac 10.5.8.
The other computer is identical, but is running on 10.5.6.
Thanks for getting back to me s quickly... I've been definitely hitting my head on this for a few days.

Hmm, never seen that one. Can you reproduce it, does it happen every time? The "org.puredata.pd.wish" part makes me think that make its the Tcl/Tk GUI side that's crashing.
Which exact version of mac os x are you running? Which hardware?

Hi List,
I'm currently running into issues with getting PD Extended 0.41.4 to run on Leopard 10.5. If I let the software run for an extended period of time (say, 30 minutes to a couple of hours) PD/Gem crashes without an error report. I'm running 1920 x 1080 video playback when this happens and I've tested the programming with both two and three layers of video running.
This is happening on a quad core Intel-Xeon Mac with 4 GB of memory (although the same issue is happening if I cannibalize an additional 4 GB), an ATI Radeon card and Blackmagic Intensity for capture. While I can't get an error report from PD/Gem, Console is giving me the following:
8/25/09 1:38:48 PM [0x0-0x18018].org.puredata.pd.wish[271] pd(272,0xa03ce720) malloc: *** mmap(size=4149248) failed (error code=12)
8/25/09 1:38:48 PM [0x0-0x18018].org.puredata.pd.wish[271] *** error: can't allocate region
8/25/09 1:38:48 PM [0x0-0x18018].org.puredata.pd.wish[271] *** set a breakpoint in malloc_error_break to debug
8/25/09 1:38:48 PM [0x0-0x18018].org.puredata.pd.wish[271] terminate called after throwing an instance of 'std::bad_alloc'
This is definitely not an area that I'm overly familiar/confident about and would really love to have at least some sort of idea of what could be causing this to happen. This error is the only error I get with my programming and it's frustrating since I can't downgrade to Leopard or run it on another operating system. Any insight into this issue would be greatly appreciated. I've altered my programming dramatically and stripped it down to the bare bones and still, I have this error occuring.
So, I suppose my question is this... is this a PD/Gem issue with Leopard? Or something on my side that I'm just not seeing... Any insight into this would be hugely appreciated....
Thank you,
J
