[Firebird-odbc-devel] ODBC 64 crash

[Laurs L. <la...@ho...>]

I have been working some years with Firebird 1.5 with ODBC 1.2

I am now trying to convert databases to v 2.5 x64 with Firebird_ODBC_2.0.1.152_x64 and 
succeded to recreate at 2.5 database with gbak 
(and I can see all data in the database with DBexplorer (old Borland 5)). 

My software is 32 bit Visual Studio C++ 2008 and I am testing it under 
Windows 7 x64.

It was all working in win7x64 with Firebird 1.5 with ODBC 1.2 under win 7x64.
I deinstalled all Firebird and ODBC and installed the 64 bit versions. 
After that:
I can connect to the database with ODBC, I can open tables, but when I read 
from them, the program crashes somewhere in the code in free(); when I frees 
the data pointers after reading data. 
The data pointers used are for Bind / Fetch like:
SQLPOINTER pdata11 = NULL; 
pdata11 = (SQLPOINTER)malloc(__iintmaxdatalen+2); 
ret = SQLBindCol(odbchnd_->StmtHandle, 
                 ivar11, 
                 SQL_C_BINARY, 
                 (SQLPOINTER) pdata11, 
                 __iintmaxdatalen, 
                 & pcbValue11
);
Its different for different tables when it crashes, but I get errors from HeapFree.
The ODBC software I use is an old example from MS (maybee MS visual 6), but it 
compiles and loads all the jdbc/odbc drivers at start.
Any ideas/help are appreciated.
