Hi,

Following steps lead to crash!
1. call SQLAllocHandle to allocate a statement handle
2. call SQLGetStmtAttr(...,SQL_ATTR_IMP_PARAM_DESC,...) to get the IPD of the stmt handle
3. call SQLSetDescField(...,1,SQL_DESC_PARAMETER_TYPE,...)
The 3rd step leads to crash.
But SQLSetDescField(...,1,SQL_DESC_CONCISE_TYPE,...) will not crash, and following call to set SQL_DESC_PARAMETER_TYPE will not crash either.

　　Regards,
