[Sbcl-devel] SBCL on AMD 64

[Nicolas N. <Nic...@iw...>]

Hello,

since two weeks ago I have access to an AMD64-machine with 16 GB memory and
I would like to solve some large problems there with SBCL.  However, I have
now run several times in errors when I really use a lot of memory (say,
more than 4 GB).

I now have done a test which simply allocates a list of 500 8MB-arrays
three times, and run into a problem already for this simple test (see
below).

Can someone help?  I have compiled this SBCL without thread support for
ensuring that the errors do not come from there.

Yours, Nicolas.
