32 bit and 64 bit freebsd binary compatiblty

[navneet Upadhyay]

Hi ,
        For our product we generally compile the binaries on 32 bit systems
and use them for both 32 and 64 bit systems. like we have same binaries for
32 bit and 64 bit RHEL.

We are porting the product to FreeBSD and when we tried the same,
i.erunning binaries compiled on 32 bit FreeBSD
6.2 on 64 bit FreeBSD system they produce *core dump.*


Any known reasons, do we have to compile binaries on 64 bit machine.

Thanks,
Navneet
