Problem using Connector/ODBC on Fedora 21

[Leo Carreon]

Hi,

For starters, I am using Fedora 21 32-bit and these are the package names and version numbers on this platform:

unixODBC 2.3.2
unixODBC-devel 2.3.2
unixODBC-gui-qt 0.10.x
community-mysql 5.6.23
community-mysql-server 5.6.23
mysql-connector-odbc 5.3.2

This is the contents of my /etc/odbc.ini file:

[odbctest]
Description=MySQL
Driver=MySQL
Server=
Database=odbctest
Port=
Socket=
Option=
Stmt=
Charset=utf8

I have setup my test database using the "MySQL" command line tool. My C++ test program is connecting to a MySQL server using Connector/ODBC. When my test program calls SQLConnect it crashes with the following snippet of a backtrace:

/lib/libc.so.6(+0x6ce09)[0xb72d6e09]
/lib/libc.so.6(+0x74406)[0xb72de406]
/lib/libc.so.6(cfree+0x56)[0xb72e2676]
/usr/lib/mysql/libmysqlclient.so.18(my_free+0x63)[0xb6ef2f43]
/usr/lib/libmyodbc5.so(MySQLGetPrivateProfileStringW+0x179)[0xb7239ca9]
/usr/lib/libmyodbc5.so(ds_lookup+0x78)[0xb72381a8]
/usr/lib/libmyodbc5.so(MySQLConnect+0xde)[0xb72147ce]
/usr/lib/libmyodbc5.so(SQLConnectW+0x52)[0xb7231ec2]
/lib/libodbc.so.2(SQLConnect+0xd10)[0xb75a86a0]

I have exactly the same configuration on Fedora 20 32/64-bit and its happily working on these platforms. The only difference I can see is the package version numbers which are:

unixODBC 2.3.2
unixODBC-devel 2.3.2
unixODBC-gui-qt 0.8.x
community-mysql 5.5.42
community-mysql-server 5.5.42
mysql-connector-odbc 5.2.5

I noticed that in either platform /usr/lib/libmyodbc5.so is a link to /usr/lib/libmyodbc5w.so.

Note that my application is ANSI, i.e. it uses SQLCHAR* when using ODBC calls.

What am I doing wrong on my Fedora 21 platform? What changes do I need to make to get this to work?

Any help will be much appreciated. Thanks in advance.
