Hello, I am having difficulties translating Pypy, but googling
searching did not reveal any mentions of similar problems, so I am not
sure what to do.
I am not able to successfully translate Pypy, using any combination of
options I have tried. Here are my results so far.
Ubuntu 12.04 64 bit
Trying to translate pypy sandbox from latest source release (I can
find the actual hash number if necessary).
I used PYPY_GC_MAX_DELTA=200MB and loop_longevity=300 as suggested to
reduce memory usage, along with -O2 and --sandbox
The translator produced an executable, but attempting to run this
executable with or without pypy_interact.py leads to an immediate
termination with the message
Fatalerror during initialization out of memory
Windows 7 64 bit
Same steps as above except without max delta, and using the 1.9 source
release.
The sandbox again fails with the Fatalerror out of memory. It also
produces some weird characters before terminating which I'm guessing
are the marshalled stdout from the sandbox.
Windows 7 64 bit
Attempt to translate plain Pypy, with -Ojit but no loop longevity.
Translation fails partway through with a MemoryError despite several
GB of free memory.
I have tried both CPython 2.7 and prebuilt Pypy binaries to do the
translating, and nothing I do will work. I can't find any mentions of
others experiencing similar problems, but the fact that the problems
show up for me with multiple versions on multiple machines with
different OSs indicates that something serious is wrong. Does anyone
have any idea what the problem might be?

What is the actual command line you are using?
Note that the last trunk known to complete translation correctly was
around July 3, version 20258fbf10d0. You can see the pypy buildbot
history at http://buildbot.pypy.org/nightly/trunk
<http://buildbot.pypy.org/nightly/trunk/> The "tip" version does not
translate, someone should fix it soonish.
To translate on windows, you must use pypy (only 32 bit is available)
or 32 bit cpython and follow the directions here
http://pypy.readthedocs.org/en/latest/windows.html?highlight=windows
especially this bit: editbin /largeaddressaware <translating python>
