my big challenge is that this problem is utterly unreproducable, down
to "crashes depend on directory in which the file rests", that is:

/mother/application/application.exe -> crashes
/mother/applicationxtra/application.exe -> does not crash.

On another reboot of the machine, also application below
applicationxtra crashes. Next reboot, both applications do not crash.
I even checked python 2.4 and python 2.5 :(

The only "narrowing down" is: the crash seems to be around

def checkDB(modus, retcn=False):
    """prüfen, ob die entspr. Datenbank vorhanden ist"""
    cn=None
    try:
        host=  u.host[modus]
        database      = u.database[modus]
        user          = u.user[modus]
        port          = u.port[modus]
        password      = u.password[modus]
        sslmode="prefer"

        g.log.info("pruefe nach %s/%s/%s/%s/%s" % (host,database,user,
port,sslmode))

        cn=psycopg2.connect(host=host,database=database,port=port,
                                    user=user,
password=password,sslmode=sslmode)
        erg=True
    except psycopg2.DatabaseError:
        erg=False
    if retcn:
        return cn
    else:
        return erg

That is: I cannot be sure if all database hosts are available, so I
try to connect and use "failure" to learn: database host not
available. And sometimes ... on some machines... the application exits
with windows-error, and digging down shows something about
"ntdll.dll", varying offsets.

My googling for ntdll.dll just gave spurios information about "memory
corruption", so... "memory corruption" and "leaks" were connected
within me.

I will compile svn/trunk and test again. If anyone can give me any
more hint to search or to make the error reproducable, please speak up
:)

Harald
