Status: Verified Impact on me:
None 
Category:Connector / ODBC Severity:S3 (Non-critical)
Version:5.3.4 OS:Windows (6.1.7601)
Assigned to: CPU Architecture:Any

Description:
Download and install the source code of ODBC 5.3.4.
CMake it and build with Visual Studio 2013 Community version.

How to repeat:
Run the tests, and it will crash.

mysql-connector-odbc-5.3.4\test\Debug> my_bulk.exe

Suggested fix:
SQLULENINTEGER numRowsFetched;

=>

SQLULEN numRowsFetched;

SQLULENINTEGER is always 32 bit, while SQLULEN is 64 bit under x64.
The same problems exists in my_crash.c and my_result2.c.

In my_result2.c, variables outlen and len should be declared as SQLLEN instead of  SQLINTEGER.  Visual Studio 2013 will output warnings during the build.  And it will cause the program crash in debug mode, too.

And in my_error.c, col_size should be declared as SQLULEN.
