Hello,

I'm having trouble with a few ODBC functions dying in nasty ways when I
call them with any of a variety of parameters. I can reproduce the problem
in a simple test script that does nothing more than set up a connection and
a statement handle and call the info function. This is on 32-bit Linux
(RHEL 5.4) with FreeTDS 0.91 and unixODBC 2.3.1.  I'm connecting to a SQL
Server 2008 instance.

SQLProcedures()/SQLProceduresW() are segfaulting and
SQLTables()/SQLTablesW() are aborting with an assertion failure. Details
below.

Any insight you can provide is appreciated,
m.
