Okay, that's not very encouraging.
I would have thought that a segmentation fault would have attracted more
attention and more answer. besides, i didn't see any issue in the bug
tracker about that. Maybe I should add one report if I find the time.

Unfortunately, I have to use Tkagg : I need to add some graphs in a Tk-based
application...

Installing a full numpy-scipy-matplotlib environment is my second goal.
I had some pb with odr and ndimage, which caused the scipy test suite to
fail, but now it works.
installing matplotlib is the last barrier.

Here are my last findings :
1) I runned my installations script on another computer, a linux 64 bit
with Red Hat linux 3, and I had the same pb.
So this bug seems reproductible and do not depend on the architecture or on
the distribution.
There's nothing really extraordinary in these script, but I can send you
them if you want.
2) I tried to compile all these programs in debug mode. I added the options
--enable-symbols when building tcl, tk and python
--with-pydebug when compiling python
--debug when builkding matplotlib.
This doesn't give more information when running `python2.5
test.py--verbose-debug_annoying`, but the backtrace in gdb is a little
longer :

I'm not used to debugging C code or to cope with segmentation faults.
Do you see anything which could give me a clue for fixing this pb ?
Thanks for the reply,
