Summary: Reference count bug in ODBC
Initial Comment:
The following code crashes -
import odbc
db = odbc.odbc('frank/Adminstrator')
def update():
c = db.cursor()
try:
c.execute("insect into fmtest values ('rubbish')")
return ['success']
except:
return ['fail']
print update()
The update routine tries to insert a record into the
database. If it fails (it will in the example as the
command is invalid), MSW pops up a box with the
message "Python.exe has generated errors and will be
closed by Windows", and the dos box displays the
message "<refcnt 0 at ....>".
The error only occurs if the return type is a list, and if
the function returns from the "except" clause.

This can be reproduced more easily:
import odbc
conn = odbc.odbc("MSSTEST")
curs = conn.cursor()
curs.description
Using PyWin 151 on PythonWin 2.1.3 (#35, Apr 8 2002,
17:47:50) [MSC 32 bit (Intel)] on win32 on Windows 2000.
