Terry J. Reedy  added the comment:

Should this be closed as won't fix? outofdate? superseded by 5504?
Does it even apply to 2.7 or 3.x?

Issue #5504 shows a possibly more future proof way to fix this issue.

Here is a patch for Modules/_ctypes/malloc_closure.c that may work
(totally untested).  The code snippet is copied from Modules/mmapmodule.c.

Thanks. None of the URLs seem to be helpful, anyway.
Please avoid posting URLs without any indication as to what
specific conclusion you like to see drawn from the page.

It seems that Solaris 2.6 just doesn't have explicit support
anonymous mmap explicitly. As a consequence, ctypes, in its
current form, just can't run on it.

A solution might be to map /dev/zero instead. Contributions
are welcome.

Can you please report from the mmap man page how anonymous mappings can
be achieved on Solaris 2.6?

  when building on Solaris 2.6 with gcc I get the following error:

Let me add that I see -fPIC in the top-level Makefile but do not know
why -static is not in the same variable as well. Anyway, it is not
a shared library problem I think as I already recompiled my bzip2,
openssl and ncurses libs with "-shared -fpic". ;-)
