loading extension problem

[Mike Rovner]

Hi folks,

I wrote an extension to my C application and it works just fine.
I used it on several computers with Solaris 2.7 and 2.8
The problem arise when I try to use it on another computer with
Solaris 2.6.
On that machine it refuses even to load. 

Python 2.0 compiled on 2.7 and seems to work on all computers.
On 2.6 it loads another .so extension (readline) without any problem.

I used WAD extension to get crash info:

WAD: Collecting debugging information...

        PyObject *kv;
        int err;
 =>     kv = PyString_FromString(key);
        if (kv == NULL)
                return -1;

Well, it doesn't make much sense for me.
May be someone can direct me.

Thank you,
Mike
