python segfaults when using Easysoft ODBC Driver

[GoogleCodeExporter]

The code I have below will crash when using Easysofts ODBC-SQL Server driver 
but performs fine using freetds ODBC driver

import pyodbc
conn = pyodbc.connect('DSN=MYDSN")
curs = conn.cursor()
curs.execute('select * from mytable')
row = curs.fetchone()
print row
# this is the point where it will segfault.

I ran this same code using gdb and I get the following backtrace.

Program received signal SIGSEGV, Segmentation fault.

As I mentioned previously this code executes correctly with FreeTDS 
TDS Version=8.0

I'm running this on x86_64 linux.

I filed this bug prematurely and I believe it is now related to another issue 
in my compilation of both pyodbc and python under a 64 bit system.

From your second comment, I assume this should be closed?  If not, please 
reopen.
