The segfault is at line:

    if (SQL_SUCCESS == ret && 0 ==
QR_get_num_total_tuples(SC_get_Result(stmt))) 

in functtion

RETCODE        SQL_API
SQLSpecialColumns(HSTMT StatementHandle,
                  SQLUSMALLINT IdentifierType, SQLCHAR *CatalogName,
                  SQLSMALLINT NameLength1, SQLCHAR *SchemaName,
                  SQLSMALLINT NameLength2, SQLCHAR *TableName,
                  SQLSMALLINT NameLength3, SQLUSMALLINT Scope,
                  SQLUSMALLINT Nullable)

in file odbcapi.c (in pgodbc sources).

In statement.h:#define SC_get_Result(a)  (a->result)

But:

(gdb) print stmt->result
$4 = (QResultClass *) 0x0


Here's your NULL pointer!
