Trap in copy_statement_with_parameters with latest sources

With the 07_01_006 driver I had problems with the abort caused by doing
SQLPrepare - SQLDescribeCol - SQLBindParameter - SQLExecute. Rows inserted
into a temp data were getting rolled back by the internal abort caused by
this sequence of calls. The Disallow Premature option in the 007 driver
cures this problem. I initially downloaded the driver installer and did a
'binary' install, but this didn't cure the problem, so I took a copy of the
latest sources from CVS and built the driver DLL myself and the problem went
away. However, I now have a problem with crashes in the driver with queries
that were OK with the 006 driver. I'm working with a large scale app and so
far haven't got a theory about which types of queries cause the problem.
It's not a trivial problem as quite a lot of fairly complex queries run OK
with the new driver. The crashes are happening at the following location:

/* make sure new_statement is always null-terminated */
CVT_TERMINATE

====> if (conn->DriverToDataSource != NULL)
{
int length = strlen(new_statement);

conn->DriverToDataSource(conn->translation_option,

SQL_CHAR,

new_statement, length,

new_statement, length, NULL,

NULL, 0, NULL);
}

Has anyone else seen this problem?
