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!

Patch to remove errant variable declarations Edit (316 bytes, text/plain)

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.
