Invalid pointer crash on CentOS 6
I'm trying to run node-oracle on CentOS 6.4, however it crashes on executing even a very simple query. My test program is:
var oracle = require('oracle');
var connString = "(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=xxx)(PORT=1521))(CONNECT_DATA=(SID=xxx)))";
var connectData = { "tns": connString, "user": "xxx", "password": "xxx" };
oracle.connect(connectData, function(err, connection) {
if ( err ) {
console.error(err);
process.exit(1);
}
connection.execute("SELECT 1 FROM dual", [], function(err, results) {
if (err) {
console.log(err);
} else {
console.log(results);
}
});
});
If I only establish the connection, the program runs fine, however when I add the query, the result is:
*** glibc detected *** node: free(): invalid pointer: 0x00007f5c28001070 ***

I'm guessing it's an issue with my system libraries, however I have no idea what to do about it. The instantclient installation is fine, as I'm able to run queries through sqlplus. Any help would be appreciated.
There appear to be at least one earlier thread relating to this (e.g., #13)
After changing the buildenv to Debug and rebuilding, narrowed the issue down to the getString() method in connection.cpp:
col->name = metadata.getString(oracle::occi::MetaData::ATTR_NAME);
A cursory Google search establishes that this is a known occi issue based on compiler migration during the 10 environment:
https://community.oracle.com/thread/572397?start=0&tstart=0 https://community.oracle.com/message/1396811
Subsequently downloaded the 10.2.0.5 occi libraries from Oracle via:
http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html
however, the embedded .so continues to have a dependence on libstdc++.so.5:
$ ldd libocci.so.10.1
linux-vdso.so.1 => (0x00007fff71bff000)
libstdc++.so.5 => /usr/lib/libstdc++.so.5 (0x00007f55b30a4000)
libm.so.6 => /lib/libm.so.6 (0x00007f55b2e21000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00007f55b2c09000)
libc.so.6 => /lib/libc.so.6 (0x00007f55b2882000)
/lib64/ld-linux-x86-64.so.2 (0x00007f55b35cc000)
Another thread seems to suggest that the x86_64 based on gcc3.4.3 exists in the 10.2.0.4 patch
https://community.oracle.com/message/4543974
However, after downloading the patch and resetting the symbolic link, the .so in the patch is likewise not x86_64:
ln -s libocci10_343.so.10.1 libocci.so.10.1 Error: libocci.so.10.1: wrong ELF class: ELFCLASS32
The next possible approach is to locate and recompile occi for _64 via:
http://docs.oracle.com/cd/B19306_01/install.102/b25400/post_inst_task.htm
Does anyone have an existing x86_64 occi.so for gcc3.4.3?
