SQLColumns crash (Access violation)

Hello,

I have some code that uses ODBC to retreive column information
from a SQL Server database. The call to ::SQLColumns succeeds.
I then bind my C variables to the HSTMT handle. I then call
::SQLFetch to get the next row. ::SQLFetch crashes with an
access violation. I am unable to debug

The same code works without issue against a MySQL database.

Has anyone ever encountered this crash?
Is there a work-around anyone knows of?

Thank you very much for your help.

I have no idea about accessing MSSQL from C, but I suspect
that without a code sample, you won't get a very useful answer - it
would help if you can clarify which client library you're using, and
also give some specific code that fails.
