compiling in amd_x64 and running in amd_x32

I am testing the Matlab engdemo.c file shipped with the student version of MatlabR14s3. Unfortunately, Matlab chose *not* to ship the 64 bit .so files with this release.

When compiling and linking on 32bit linux everything works fine! Engine starts and demo works great.

I next reboot into 64b mode and when I run, I get an error that the matlab
engine did not start.

I also recompile under 64 bit linux using -m32 flags and everything compiles and links fine. When I run, I get the same can't start engine error.

Seems like there is some aspect of the environment that is not properly supporting 32b applications, even though I'll installed the 32 bit environment support libraries under linux.

Any ideas how to go about fixing this problem?

Thanks.
