[Bug 724517] Re: isql segfaults in batch mode

[Kyle Strickland]

I don't know why I didn't see this before, but the bug seems to come
from an extra variable declaration in an inner scope.  Removing that
declaration fixed the problem.

Title:
  isql segfaults in batch mode

Status in “unixodbc” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: unixodbc

  Ubuntu 10.10, unixodbc_2.2.14p2-1ubuntu1

  Steps to reproduce:
  * run "isql -b MyDSN MyUID MyPWD"
  * enter any SQL statement on one line, or nothing at all
  * press Ctrl-D (EOF)
  "Segmentation fault"

  I had this occur both with FreeTDS and with IBM iSeries ODBC driver.
  Crash occurs at line 264 of isql.c, apparently due to a null pointer
  dereference.

  Thanks!
