Someone else suggested a WDT issue, and I might be inclined
to agree.

Did you include the "DEFINE NO_CLRWDT 1" statement?  If
you did, did you make sure that the Watchdog timer bit was
cleared in the configs?  It might be a good idea to clear it
anyway.

As for a problem writing the 8-bit value into a 16 bit variable,
I don't think that's a problem, but you can circumvent it by
doing this:
RND.byte1 = 0
RND.byte0 = TMR0
... etc. in place of the RND = TMR0 statement.
