[Python.NET] Q2: py.net problems w/python 2.6.2

Could anyone conveniently try python.net with python 2.6.2? I am seeing
two fatal problems in my lightly-patched python.net.

I'm using ubuntu 9.04
python 2.6.2
python.net 2.0 alpha2 with Borzenkov's suggested PYTHON25 -> PYTHON26
changes and Feihong Hsu's changes
mono 2.0.1 (this is the what mono --version says, which I think is
packaged as distribution 1.9.something?)

For all of this I'm using the python.exe that gets built alongside
python.net, because ubuntu's python environments are irritatingly built
with --disable-shared

import clr
import System
STR = System.String('hithere')

I get a fatal error "GCHandle value belongs to a different domain"...
this is being thrown by the coercion of an IntPtr to a GCHandle, from
within the coercion operation in ManagedType.GetManagedObject.

import clr
from System.Drawing import Point
p = Point(5,5)

then I can

p.X

p.Y

p.ToString()

u'{X=5,Y=5}'

dir(p)

['Add', 'Ceiling', ..., '__class__', ...]

p.__class__

dies in the most awful way, dumping all thread stacks and killing mono
and python. I get a message saying "Got a SIGSEGV while executing
native code. etc."

If anyone has any clues about this, I'd love to hear them. My current
plan is to install python 2.5.x as an alternate python, rebuild against
that, and see if that works, and then perhaps dig into this further. I
might also try 2.6.4 since someone on the list recently asserted they
had it working with that.

thanks,
hamilton

I might be able to find time to test on windows tomorrow. Remind me
if you haven't heard.

I'm currently running Python.NET in Python 2.6.2 on Windows for a few
weeks. I tried your sample code, and everything works fine. I'm not
using Mono though, but regular Microsoft .NET.

I had a few issues at the beginning, as my (patched) version of
Python.NET was not up to date with the Python.NET trunk. My vendor
branch tells me I updated from Python.NET rev.98 to rev.101 and my
problems went away (for now).

HTH,
Nicolas.
